Jennifer Aniston and John Mayer? Don't rule it out.

MSNBC reports the two were spotted together on April 25 in Miami, where they shared lunch at Michael's Genuine Food & Drink in the Miami Design District, and then had a long dinner together at Casa Tua in South Beach.

Aniston, who at 39 is nine years older than Mayer, has been in Miami shooting "Marley & Me" with Owen Wilson. A source close to Aniston says not to read too deeply into anything at the moment, but don't count out a relationship, either.

"Jen is definitely ready to be in a solid relationship. And she's not interested in a traditional Hollywood guy, that is for sure. This might seem like a strange match on the surface, but it could actually work," said the source.
