First Lady Michelle Obama has hand-chosen Jessica Simpson to perform for military families April 13 in Denver, CO.

Simpson has performed for troops overseas and in the US. She commented on the opportunity saying, "[The First Lady] asked me to sing for the troops. That's a huge honor for me. Just to be there and show my support and say thank you."

The performance will take place during the Rockies vs. Mets baseball game and is just one event on the roster for Mrs. Obama and the vice president's wife Jill Biden's program to honor America's service members.

Simpson visited troops in the Persian Gulf in October. After her time aboard the USS Harry S. Truman she tweeted, "I'm forever changed after this last week."

Gwen is one hot stroller mamma!

The gorgeous No Doubt singer took little Kingston and Zuma to the zoo Sunday, with a pal and a nanny in tow for some extra help.

The adorable boys had a blast visiting all the animals, but they especially loved the elephants (click through our pics to see the kids checking them out).



At the end of the day, the boys were tuckered out --but luckily, they got a mini police escort to speed them right though the crowds. It's good to be a Stefani-Rossdale!

Kevin, you're making the jokes too easy for us! Pregnant Victoria Prince looks so cute and super healthy and she definitely has that glow ... but Kev, it's time to shape up! Hit the baseball field with the boys!

The parents-to-be (Kevin for the fifth time!) brought Sean Preston to the Westhills Yankees Little League game Sunday and poppa KFed was decked out in a team jersey and cap, as usual.

Go, Yankees! And go, Kevin! To the gym ...

We knew he was obsessed with Hummers, but who knew he needed this 1940's relic for a quick spin around Brentwood???

Khloe Kardashian and Lamar Odom made an appearance on The Ellen DeGeneres Show to chat about their new reality show, Khloe & Lamar.

But Khloe admits she wasn't really into having another show, after years of shooting with her family, and constantly having crews all up in her personal space. Kardashian shares:

Khloe: It's a lot. I mean, I knew from doing my family's show how intense and grueling and how much they are really in your face. I personally
didn't want to do the show. I love taping. I just didn't want to put
Lamar through that pressure and Lamar was like, let's do it. Everyone
keeps asking let's do it.
Lamar: I thought it was going to be easy. It's really tough.
Khloe: He did. Three days into it. He asked, he said, can you tell your mom to get us out of this contract. I go, absolutely not. I go, nope, that ship has sailed. I told you. Lamar is great and he loves the finished product and we have
really expensive home videos...

Check out a preview of Khloe and Lamar's first season, after the jump ...

Eva Longoria may have spent the week promoting her cookbook, but it looks as if things are getting hot and heavy outside of the kitchen as well!

Eva and new beau Eduardo Cruz snuggled up to each other during a romantic lunch in Hollywood this week.

And even though Eva isn't dishing about her new relationship, she says she has "no regrets" about her old one.

“No regrets," she told Joy Behar on her show Friday. "It’s funny because I have tattoos too. I have my wedding tattoo – it’s 7 – 7 – 2007 — the day we got married."

But Eva says she has no plans on removing it anytime soon. "I like it… I’ll just put the divorce date and it’ll be like a gravestone!” Eva joked.

Wonder how Eduardo feels about that?

Tom Cruise and Katie Holmes both went incognito in sunglasses, a cap (for him) and a head scarf (for her) while driving to the gym this morning in Los Angeles.

Katie looked understandably upset after her Kennedys mini-series failed to sustain record-breaking numbers on its first night and dropped 35% on it's second night.

The mini-series has been fraught with issues after it was dropped from the History Channel and struggled to find a home. Eventually Reelz picked up the series, which stars Katie as Jackie and Greg Kinnear as JFK, and although it put the channel on the map, hasn't received the greatest reviews.

Hopefully Holmes will have better luck with a couple of high-profile projects coming soon. Katie next appears in Jack and Jill with Adam Sandler, and will be returning to the Batman franchise in The Dark Knight Rises, playing her own character's mother in flashbacks.

After famously replacing Mel Gibson in the popular movie sequel when castmembers objected, Liam Neeson has been cut from The Hangover Part II.

Neeson had already shot his scenes as a Bangkok tattoo artist, but due to scheduling conflicts, the actor had to be replaced himself when the film was forced to do re-shoots.

Director Nick Cassavetes (The Notebook) was called in at the last minute when Liam's work on The Clash of the Titans sequel prohibited him from participating.

“We were in a complete time crunch so I called up Nick and asked if he would do the part,” The film's director Todd Phillips told Variety. “He came in and crushed it and that is the scene that you will ultimately see in the film. [I’m excited for everyone] to see the film. It turned out great.”
