Affleck, 48, appears to have splurged mightily on the birthday getaway for JLo, who celebrates her 52nd birthday on Saturday, sparing no expense as the couple openly displayed their affection.

After flying in to the French Riviera on a luxury private jet, likely a Bombardier Global 7500, at an estimated cost of around $200,000, the couple known as ‘Bennifer’ were quickly whisked away to a luxury $130M mega-yacht, named Valerie, in the Mediterranean, where they were spotted exchanging kisses and tender embraces on the sun deck.

‘Fifty two!’ declared Lopez in an Instagram video, proudly flaunting her figure in a bikini and elegant flowing beach wrap as she strutted on the deck of the yacht.

It is not known who is paying for the trip, but Affleck is said to be worth $150m while JLo is around three times that at $400million.
