Aniston and Mayer Heat Up

Unlucky-in-love Jennifer Aniston was caught in the midst of a hot-n-heavy weekend with serial-dater and musician John Mayer, In Touch magazine reports. Mayer flew to Miami where America's Sweetheart was filming Marley & Me. "It's very real. They've been seeing each other for a few weeks now,” a source close to Mayer told People.

The canoodling couple stayed at her Mandarin Oriental Miami presidential suite, sunbathed, and huddled over romantic meals all weekend. Mayer, 30, has pursued his fair share of older stars, including Ricki Lake, 39, and Cameron Diaz, 35, but has his sights on Aniston, 39, who hasn’t been in a serious relationship since splitting with Vince Vaughn in 2006.
