Gisele Bundchen wore a tiny bikini this afternoon while lounging by her hotel's pool in Rio. She and her husband, Tom Brady, arrived in Brazil yesterday, but it was a different male pal who was shirtless keeping her company today. Gisele and Tom are there to have fun during the Carnival festival, after she was there just last month to walk the runway for Colcci during Sao Paulo Fashion Week. Busy Gisele has also had time to hit the gym regularly, and she showed off the results of her hard work in a recent spread for V.

Kate Hudson threw on a her TEXTILE Elizabeth & James sweater yesterday afternoon while out in LA. She and her ex Chris Robinson reunited to watch their son Ryder's baseball game, and Kate's parents Kurt Russell and Goldie Hawn also turned out for the sporting event. Kate's current flame, Matt Bellamy, wasn't able to attend — he was recently in his home country of the UK to pick up an award for his hotness at the Shockwaves NME Awards. Kate's apparently planning to spend more time in England herself after purchasing a home in London, but Matt's no stranger to stints in California. He and Kate were memorably together just last month for a sweet appearance at the Grammys, where Matt gave her a shout-out from the stage and all eyes were on her bump-hugging Cavalli gown.

Miranda Kerr and Orlando Bloom wrapped up their stay in Paris yesterday and caught a flight out of the Charles de Gaulle airport. Their young son Flynn was ready for the trip in a baby blue onesie, and we got our latest look at his adorable face — he already seems much bigger than our first glimpse of him back in January. The trio was in France so Miranda could make her big return to the runway at the Balenciaga show during Fall Fashion Week. She also had a chance to run errands solo in the city, while Orlando and Flynn enjoyed some guy time out on a walk.

Patrick Dempsey got behind the wheel yesterday at the Homestead-Miami Speedway in Florida. The sporty Grey's Anatomy star and former sexiest man alive contender strapped on a helmet and indulged his need for speed during his day at the track. Patrick, who helped raise money for his philanthropic causes at the celebrity-studded event, likes getting physical and he's frequently spotted hopping on his bike for charity rides. Patrick will also have a chance to get back in action on the big screen soon, too, with his role in the upcoming Transformers 3.

Gwen Stefani stepped out in black and white to run errands in Sherman Oaks on Thursday. She recently returned home from a trip to NYC, where she continued displaying her love for prints during her L.A.M.B. show at Fashion Week with the help of her oldest son Kingston. Gwen will be able to focus on her musical career with more studio time now that she's back in California, though she's also been taking care of her mom duties — she and husband Gavin Rossdale brought Kingston and Zuma over to Jennifer Lopez's house last weekend to celebrate J Lo's twins' third birthday.
