Suri Cruise lounged outside while Katie Holmes sat nearby in LA yesterday. The little one opened up gifts while surrounded by family and friends during Suri's 5th birthday party. We celebrated her big day with a look back at Suri's five fun years of travels! The milestone has been a hot topic for the Holmes-Cruise crew, as Katie's been sharing her exciting plans for the big day all month long. The weekend wasn't all about Tom and Katie's youngest daughter, though, since the busy parents attended producer Brad Grey's wedding on Saturday along with other A-listers like Brad Pitt, Jennifer Lopez, and Gwen Stefani.

Orlando Bloom sweetly kissed his son Flynn as they walked through LAX today. The boys were joined by mom, Miranda Kerr, who donned a bikini yesterday during a beach-side Victoria's Secret photo shoot. It's been just three months since Miranda gave birth to Flynn, but she looked amazing modeling an extremely tiny two-piece. Miranda and Orlando's little one is becoming a well-accomplished traveler, having already made a cross-continental trip to France. During their trip abroad, Orlando and Flynn explored the City of Lights while Miranda made her return to the runway for Balenciaga during Paris's Fashion Week. The trio may be heading to the Big Apple this time around, as Orlando's expected to make an appearance this Friday at the Tribeca Film Festival's premiere of The Good Doctor.

Kristen Stewart made a low-key appearance at the party for Robert Pattinson's Water For Elephants premiere in NYC last night, but there was nothing discreet about the hot kiss they shared when they hopped into their car afterward — we even have video of Robert and Kristen kissing! She was spotted leaving the bash with Robert, holding onto his arm and wearing a hot dress that was reportedly designed by J. Mendel. Robert, meanwhile, was dashing in his tux, and we even managed to snag a minute with him on the red carpet before the screening began. Robert and Kristen's hot evening out on the town didn't get in the way of him rising early this morning to swing by the Today show. It looks like Kristen was able to visit the Big Apple to support her man during his final week of press before his movie with Reese Witherspoon opens this Friday. Kristen and Rob were also able to spend the last few weeks together up in Canada, where production is wrapping up on Breaking Dawn this week.

Miranda Kerr wore a bikini and showed off her enviable abs yesterday during a photo shoot. A few assistants helped barefooted Miranda navigate the rocky Malibu beach as she got ready to pose for the steamy pictures. Miranda didn't waste time getting back to modeling after she and Orlando Bloom welcomed their son, Flynn Bloom, in January. She made her return to the runway in Balenciaga's show eight weeks after welcoming her little guy to the world. She even teamed up with her fellow Victoria's Secret Angels to toast the launch of the brand's SWIM line in LA last month. Miranda is easing back into work, but she and Orlando have also been spending long hours with their addition between business-related travels and social outings with friends. She's also apparently still able to brush up on her reading despite her new mom duties. Miranda Kerr shared her favorite books on her blog, writing that she loves Catcher in the Rye, Siddhartha, and The Autobiography of a Yogi.

Ben Affleck picked up his car from a valet stand this morning after running an errand in LA. He spent the weekend celebrating with wife Jennifer Garner as she turned 39. In honor of her big day, Ben, Violet, and Seraphina treated Jen to a family dinner on Saturday and followed it up with a large backyard bash for their friends and family yesterday. Ben's pal Matt Damon dropped by Jennifer Garner's party with his wife, Luciana, and their daughters Gia and Stella. Ben is back with his three main ladies following a recent scouting trip to Turkey, where he also spent time checking out flooring options at a local rug store. Ben's next film, an untitled project by Terrence Malick, is set to open in 2012; however, the director will debut his highly anticipated Brad Pitt film Tree of Life next month at Cannes.
