Jennifer Aniston and John Mayer continue to fuel speculation they're dating – this time by reportedly making out at the wrap party of the actress’s new movie.

Following a second romantic weekend together, the couple attended the wrap party of Aniston's upcoming film, Marley & Me, at Nikki Coconut Grove, where Mayer shielded the former Friends star from the paparazzi as she climbed out of a car.

The two reportedly shared kisses at the lounge, where they listened to a DJ play '80s music hits before heading back to their hotel.

The pair sent gossips into a frenzy after they were seen embracing on a Miami, Florida beach last month.

Mayer the Player later hinted the rumours are true - insisting the camera never lies - but the stars have yet to confirm their relationship.

And on Saturday, they were photographed enjoying another romantic tryst at the Mandarin Oriental Hotel in Miami, Florida.

In the photos, Aniston, 39, and Mayer, 30, are sitting in poolside lounge chairs, eating salads and whispering into one another's ears, reports People.com.
