Jen and Ben were photographed - in pictures obtained by MailOnline - at the singer's private Florida residence earlier in the week after weeks of sightings in Los Angeles.

JLo, 51 was all smiles as she walked down a flight of stairs outside, while the Oscar-winning actor followed close behind. The famous exes are believed to have rekindled their romance years after calling off their engagement in 2004.

They are yet to publicly comment on the reports but have been pictured in recent weeks at Jennifer's Los Angeles home, Los Angeles hotels, and on a trip to Montana. They also both attended the VAX Live: The Concert to Reunite the World event.
