Hilary Duff isn't afraid to break a sweat ... even while pregnant!

Mike Comrie's wifey, wearing sweats, funky shades and black toe nail polish, looked picture perfect even after hitting the gym. Way to work it out, Hil!

The Duffster, barely showing a baby bump, still has over 6 months to go in her pregnancy. We're so excited for her.

Our photogs caught up with the just-announced cast members of Dancing With The Stars on Tuesday, and former talk show host Ricki Lake was excited to get started as she headed to the dance studios!

In a video posted to her Twitter account, Lake reveals that she is "terrified" to do the show! She says:

"I'm not a trained dancer -- I have no idea what I'm doing! I'm hoping to channel Kirstie Alley -- she was a big inspiration for me last season."

Alley sent a supportive Tweet back, saying, "@RickiLake .....Girl, Rock that party hard!!! Show em how it's done....Love, Mommy...;)"

Lake's been Tweeting like crazy since the announcement. See the pics she sent out of her and contestants Rob Kardashian, Nancy Grace and David Arquette after the jump!

Rob Kardashian will be on the upcoming 13th season of Dancing with the Stars, but it turns out it's not by choice - his mom is making him do it!

Rob told reporters Monday night:

“Yeah, my mom pretty much forced me to do this show. She did the same thing to Kim and now she’s doing it to me.”

Continuing to slam his family, Rob went on to say that he's not taking anything big sis Kim Kardashian has to say to heart, even though she hoofed it on DWTS back in 2008. “I don’t think I need advice from someone who lasted, I think, three weeks,” Rob said.

Ouch! That's a pretty extreme contrast from what Kim had to say about her brother. She Tweeted:

"So excited my bro @RobKardashian is gonna be on Dancing With the Stars! Good luck Robbie! I just hope u do better than me...not too hard!LOL"

Well, soon we'll see if Rob can make it on the show longer than Kim did!

LeAnn Rimes' ex-husband, Dean Sheremet, has married fiancee Sarah Silver at a City Clerk's office.

Sheremet, 30, a chef at Nougatine at Jean-Georges in New York City, posted a video to his blog of he and Silver, 35, waiting to get hitched.

Another post on the blog shows photographer Silver taking pics -- Sheremet writes, "Taking photos at her own wedding! She can't help herself."

The couple became engaged in November of last year after going public with their relationship in July.

Congrats!

Another day ... another photo shoot for Lindsay Lohan!

The 25-year-old starlet, sporting blonde wavy locks, looks Old Hollywood glam once again for a sexy spread. While having her nails painted, Lilo Tweeted the above photo and the following: "Work work work! :)"

Linds' career seems to have changed from actress to model. Strike a pose!

What do you do when everyone's questioning every move you make? Smile, smile, smile!

At least that's what a skinny-looking Dina Lohan did while visiting a friend in Los Angeles Monday ... and wearing a super short blue dress!

The last few days have been even crazier than usual for Lindsay Lohan's mom. First, Dina was Lilo's date to Kim Kardashian's wedding in Montecito, Calif. August 20. Later that week, word got out that the New York native is trying to raise $5 million to produce a movie that would star her oldest son Michael Lohan.

And now, Dina's youngest son Cody has been receiving threatening phone calls. Nassau County police have been surrounding the area near the Lohan's Long Island home, but Dina is still in Los Angeles and not back on the East Coast with her sons.

Do you think Dina should still be in L.A. and not with Cody, even if she's in California for business?

Finally, a modeling gig that won't be surrounded by controversy!

Kendall Jenner is giving us a behind-the-scenes sneak peek of her sparkly and sweet weekend photo shoot for prom dress designer Sherri Hill.

The 15-year-old model posed in a number of adorable dresses, including the amazing silver floor-length stunner above, a sequined blue mini and a beige tulle dress that came complete with a peach bow.

"We shot over two days and I got to wear the most gorgeous prom dresses and work with a really great team," the reality star blogged.

Gorgeous indeed, Kendall!

Rachel Zoe, husband Roger and their nanny took baby boy Skyler shopping (her fav activity!) at Malibu Country Mart on Monday.

Of course, Malibu Country Mart probably isn't stylist Zoe's top shopping destination, but she made up for it later that night when she presented Roger with a Cartier ring!

The couple were celebrating the 20th anniversary of their first date. Zoe Tweeted, "Nothing like another piece of Cartier LOVE for my @rbermanus! XoRZ."

See a pic of Rachel, Roger and the ring after the jump!
