Hilary Duff shared the first picture of Luca Cruz Comrie today! She gave birth to the baby boy just two weeks ago, and expressed her excitement over his arrival on Twitter. Hilary also showed off a snap of Luca's little feet yesterday, and this afternoon she gave her fans another sweet peek at her son with Mike Comrie.

Hilary is already getting back to working out after welcoming her first child. On Saturday, she tweeted, "20 minutes on the elliptical seems like an eternity!!!" and yesterday added, "Did a little Pilates today. Felt so good to stretch! Little man had a visit with grandma and did so well! I'm lucky to have my fam so close."

Gwen Stefani wore a bikini top yesterday to hit the beach in Mexico with her family. Her husband Gavin Rossdale was shirtless for the sandy adventure, and the duo had the help of a nanny keeping an eye on their young sons Kingston Rossdale and Zuma Rossdale. Gwen jetted South of the Border to meet up with Gavin, who's been on tour with Bush. Their show schedule had Gavin all over the globe in recent weeks. After a quick stint in LA shooting a small role for Sofia Coppola's The Bling Ring, he went to London for a few days. Gavin's happy to have the break with his loved ones. On Sunday, he took to Twitter to write, "Mexico rules — finally decompressing —  what an odyssey just getting here." The Stefani-Rossdales may be able to spend a week in Cabo. His next concert isn't until a week from today in Moline, IL.

Eli Manning showed off his Super Bowl-winning physique with a shirtless dip in the pool at his Miami hotel on Monday. The 31-year-old star quarterback is in Florida enjoying a getaway with wife Abby and daughter Ava. Eli was adorable playing with Ava in the water at the pool and in the ocean alongside some friends. Eli even gave his 11-month-old baby a ride on his shoulders. He's coming off a banner season, bringing his second ring to NYC and the Giants, but there are big changes afoot for the Manning family in 2012. Eli's older brother Peyton will be moving from the Indianapolis Colts to the Denver Broncos this Fall. Eli may have lost to Tom Brady in our hot QB faceoff, but in real life, the younger Manning is still celebrating his latest triumph.
