The temperatures are rising along the East Coast and Whitney Port took advantage of the sunshine yesterday relaxing poolside at one of her favorite spots in Miami. The City star is enjoying her trip with costar Roxy Olin, though, the girls are definitely feeling the effects of the sun today. Whitney's in town to show her latest designs at Miami Fashion Week, but there's always time for a pool break. Whitney's not the only one showing off her bikini body this week with the cast of Modern Family heading to Hawaii for beach time fun, Kim Kardashian and Reggie Bush kissing in Costa Rica, and Michael J. Fox frolicking in the water in St. Barts.

Modern Family's Sarah Hyland and boyfriend Matt Prokop continued their Hawaiian vacation Monday with another PDA filled afternoon walk on the beach. The rest of her cast joined them over the weekend for some fun splashing in the waves as they all stripped down to their suits for a dip. On the show, Sarah's character Haley may need a bit of a reality check at times, but in real life the 19-year-old actress is at a career high as a Hollywood up-and-comer.

Michael J. Fox and Tracy Pollan were back at the beach in St. Barts today, only this time she traded her hot bikini for a one-piece. The happy couple lounged and read during their perfectly relaxing-looking tropical trip. The two will be headed to NYC on Friday where Michael is set to be honored and the two will be showing off their fresh vacation glow.

A shirtless Michael J. Fox and Tracy Pollan hit the waves together in St. Bart's yesterday. She looked fantastic in her bikini, holding hands with her husband of over 20 years. They'll be back in New York by Friday, when Michael will be honored with an honorary doctorate from Sweden's Karolinska Institute for his work helping raise awareness and donations for Parkinson's Disease. This comes after his appearance at the Olympics in his native Canada, but he managed to squeeze in a tropical break between cold weather obligations.

Kim Kardashian showed off her very famous bikini body - both front and back - cuddling up with shirtless Reggie Bush in Costa Rica on Saturday and Sunday. That Super Bowl-winning six-pack is certainly a welcome sight, and reminds us of their very sexy GQ spread last year. The two have been spending lots of time together since his season ended, including a couples pampering session with a head massage for Reggie. Scott isn't the only Kardashian boyfriend getting heat these days, but it looks like everything is going great with Kim and Reggie on their exotic romantic getaway.
