Catherine Giudici

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!

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.

With news that Brad Pitt and Angelina Jolie are married (SURPRISE!) we started thinking about the many, many celebrity weddings we've witnessed over the years.

And man, have we witnessed a lot of celebrity weddings!

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.

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.

Catherine Lowe (formerly Catherine Giudici) wants to be on Dancing With the Stars, and she's not being shy about broadcasting that career aspiration.

While watching this week's Dancing With the Stars results, she took to Twitter to join the conversation, and plugging herself as a future cast member.

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.

The Bachelor winners Sean Lowe and Catherine Giudici said "I do" during the franchise's first-ever live TV wedding on January 26. It was a fairy tale event.

The duo's Bora Bora honeymoon looks like it was equally magical.

Catherine Giudici is officially a Lowe. The Bachelor winner took her husband's last name following her fairy tale TV nuptials with Sean Lowe last month.

Sean Lowe and Catherine Giudici tied the knot Sunday night, and shortly thereafter, were grilled about whether they really waited until then to have sex.

Not just grilled, but put to the ultimate test - a polygraph test - by Jimmy Kimmel.

After getting engaged on The Bachelor Season 17, Sean Lowe and Catherine Giudici are married! The two tied the knot in a special ABC TV wedding Sunday.

Going up against a Lorde Grammy performance and countless other moments from the music bonanza didn't help the ratings, but it's official just the same.
