Sean Lowe

Be warned, folks -- there are some The Bachelor Spoilers in this post.

Arie Luyendyk Jr.'s explosive choice -- and then his jaw-dropping and frankly horrifying decision a few weeks after the finale was filmed -- have been aired.

The Bachelor Nation baby boom continues as Sean Lowe and his wife, Catherine Giudici, welcomed their first child over the weekend!

Catherine Giudici and Sean Lowe shared life-altering news with fans on Tuesday afternoo:

They are expecting their first child together!

Sean Lowe has some words for Kaitlyn Bristowe and Shawn Booth if they want to make it to the altar, and his advice is profound in its simplicity:

WORK it.

Catherine Lowe (formerly Catherine Giudici) of The Bachelor fame is expecting her first child, but in a shocking turn of events, the father is NOT Sean Lowe!

You won't believe who knocked her up ...

Suffice it to say, Sean Lowe's reaction to The Bachelorette's big twist this week was not positive. In fact, the former star of The Bachelor calls it "disgusting."

The Bachelor's Catherine Giudici and Sean Lowe are head over heels in love, enjoying marriage, and looking to start a family sooner rather than later.

Not shocking if you know Sean and Catherine. These two basically reside on Cloud Nine, which might get irritating if it weren't so darned adorable.

The Bachelor stars Sean Lowe and Catherine Giudici may have had an unconventional love story, but the bond they found was unconditional, and everlasting.

It's hard to believe it's been 17 months since he proposed on The Bachelor season finale. Clearly, the honeymoon phase isn't over, nor will it be anytime soon.

Former Bachelor star Sean Lowe has the distinction of being the only one of 17 stars of the ABC franchise to marry the woman he chose on the finale.

That's right, The Bachelor is 1-for-17, or 1-for-18 if you count total seasons and both of Brad Womack's failed attempts at finding love, in that regard.

Saying no to sex when so many fans freely offer up the goods takes serious dedication to one's beliefs, be those beliefs religious, moral, or just plain good sense.

Many celebrities, male and female, find themselves with a choice of bedfellows on any given night and while some of them take advantage of the revolving door of diddles, others prefer to keep their number of sexual partners low. Perhaps even in the single digits. Like as in a single person.

Juan Pablo Galavis could learn a few things about being The Bachelor from his predecessor Sean Lowe, who, as nice as he is, took him to task this week.

Lowe, who married his final rose recipient Catherine Giudici, started out by defending Galavis' decision not to propose to Nikki Ferrell on the season finale.

Some celebrity couples you see and they just make you scratch your head. Others might be hotter than blazes, but you know they will fizzle out soon enough.

The best of the best, though, are built to last, proof that you can still find your best friend - and long-term romance - in the glitz and glamor of Hollywood.
