Dancing with the Stars

Justin Bieber may or may not have knocked up a 20-year old from California named Mariah Yeater.

But the artist definitely performed on Dancing with the Stars last night!

Joined by Boyz II Men, the iconic crooner debuted a new spiked haircut and sang another track off his recently-released Christmas album. It's titled "Fa La La," it's likely to make all the girls go "rah! rah! rah!" and you can watch the live performance now:

Who got voted off Dancing with the Stars this week, meanwhile? Find out now!

After Monday performances that saw Ricki Lake cement her frontrunner status on Dancing With the Stars, the question was who would join her in the final five.

With Lake amassing a huge lead and fan support, J.R. Martinez a virtual lock (no way he's going home after one off week that wasn't even that off) and Rob Kardashian looking increasingly strong each week, it came down to these three contestants ...

Was last night the end of the line for Hope, Nancy, or David?

Hope Solo continues to improve, but not fast enough for the judges' liking (sorry Maks). David Arquette has been good, not great. Nancy Grace? Just bad Monday.

So which one of them got the heave-ho?

Follow the jump to find out here ...

Call it the DWTS version of the Sports Illustrated or Madden curse.

Actor and Iraq veteran J.R. Martinez, who has tied Ricki Lake for first place in previous weeks and held the top spot when she hasn't, fell a bit short of expectations last night, right after appearing in a glowing cover story for People magazine.

Nevertheless, his score of 25 was far from shabby - even if it his recent efforts made it feel "substandard" as Len said - and he likely won't be punished by viewers for the group dance that netted him a modest 23 for 48 points in all.

Take a look at J.R. Martinez and Karina Smirnoff's routine Monday:

Each of the six contestants performed two routines on Dancing With the Stars Monday: One with their professional partners, and a team dance with two other couples.

Despite a rib injury, Ricki Lake wowed with both renditions.

She performed two paso dobles: One with partner Derek Hough and another with her team that included soccer champ Hope Solo and reality star Rob Kardashian.

Judge Bruno Tonioli described the group routine as "powerful, moving, and dramatic" and called Lake's dance with her partner "another incredible performance."

Watch her strut her way into first place right here:

Maksim Chmerkovskiy largely kept a very low profile this week.

On the heels of laying into the judges for their critiques on Dancing With the Stars a week ago, he was more or less reserved this week. Except in rehearsals.

Last night, viewers saw a clip from a group rehearsal in which Maks got aggressive with partner Hope Solo, at one point appearing to push her in the shoulder.

He was then shown exiting the room, leaving others uncomfortable. But Hope says she has no problem with Maks' teaching style - in fact, she encourages it.

"Obviously it's working," she said backstage. "We're here for the 7th week. We're getting OK scores. You wouldn't want to see me if he wasn't tough on me."

The judges praised Hope's improvement this week, so there's something to it. Check out their routine below and see the soccer star in action with Maks ...

Rob Kardashian danced up a storm on Dancing With the Stars last night.

It was a breath of fresh air for his family and all they're going through.

While sister Kim Kardashian was making a dash for the airport amidst her divorce filing, Rob made it clear that he and the whole family are behind her no matter what.

"My sister is obviously going through a lot and we're obviously very supportive of whatever decision she makes. We're here for her, to be on her side for whatever."

His Halloween-themed routine offered Kim plenty to smile about:

Rob praised his partner Cheryl Burke and the designers, saying the costumes, hair and makeup were so good that the show "deserves an Emmy" for the episode.

We'll see about that, but his oldest sister Kourtney Kardashian, her baby's father Scott Disick, and their cutie son Mason seemed to approve from the audience.

David Arquette was dressed like a magician vampire on Dancing With the Stars last night, and while his routine wasn't pure magic, it certainly didn't suck.

The judges were spellbound by his performance, giving him eights.

Head judge Len Goodman even said on Halloween: "There were lots of tricks and lots of treats. I tell you what, you've turned yourself into a dancer here."

"You needed a bit more rhythm, but overall well done to you."

David Arquette on Dancing With the Stars (Week 7)

Proving they're still a strong family despite filing for divorce, estranged wife Courteney Cox and daughter Coco were there to cheer David on as usual.

Camp choreographer Bruno Tonioli added: "You've got the prestige, you're a natural at turning tricks." That's what they said about Jasmine Waltz ...

Anyway, Arquette's team lost the team dance-off, so he's still near the bottom of the Dancing With the Stars scores this week. Think he'll be safe?

Nancy Grace is great at blowing smoke about Amanda Knox or Casey Anthony.

She could not catch fire on Dancing With the Stars Monday night, however.

Despite wearing a red wig, red eyelashes and a flirty, fringed dress ... her jive just didn't ignite very well at all. “This wasn’t a good dance for you,” judge Len Goodman said, not mincing words as always. “It was a disappointment for me.”

She earned 21 points for it, giving her 44 out of 60 for the evening. That has her in last place. Think she'll be going home tonight? Watch her possibly final routine below:

The seventh week of Dancing With the Stars' 13th season saw the return of the group dance, along with some decidedly spooky performances on Halloween night.

Who sizzled? Who fizzled? Could anyone top J.R. Martinez and Ricki Lake? Was Maksim Chmerkovskiy heating up the dance floor instead of just getting heated?

Let's find out in THG's weekly DWTS recap ...

Ricki Lake, showing off the results of her recent weight loss, turned in her best dance, paso doble that showed no evidence of the nerve injury she's been fighting.

No 10s for her (or anyone), but she stole the show, as usual, posting the best solo score of the night (27) and helping her team earn a 3-point group dance win.

J.R. Martinez, thought of by many as her chief challenge for the Mirror Ball, didn't quite match Ricki Monday. Len Goodman called his performance "substandard."

DWTS also aired video of J.R. and Karina Smirnoff getting testy backstage, though they ended up working it out and hugging it out. We think he'll survive tonight.

As for the rest of the field? Rob Kardashian isn't going anywhere, either, turning in his best dance of the season on the same day Kim Kardashian filed for divorce.

Dancing With the Stars' 13th season sure got interesting last week.

Chaz Bono was eliminated after a good run, but did not leave on the best of terms after what he felt were unfair comments (not scores) from the judges.

On a similar note, Maksim Chmerkovskiy went off on the judges following their critiques of Hope Solo, then called out Derek Hough for siding with them.

Then there was Kim Kardashian's fake Tweet vote-getting scam.

Bottom line, it was a crazy week. How will tonight's performances stack up? Will the DWTS judges cool their heels a bit or can we expect more sparks to fly?

Can anybody stop Ricki Lake or J.R. Martinez from winning it all? At this point it looks like the only race is for the third spot along side them in the finals.

Expecting the unexpected is the name of the game, however, and there's no telling what we can look forward to when the top six take to the parquet tonight.

The field has now been cut in half. It's go time, people. So we ask:

Who will hoist the Mirror Ball on Dancing With the Stars?
