The “Gossip Girl” star was photographed last Saturday at Rio de Janiero, Brazil having a great time under the sun and doing some much needed PDA with her boyfriend, Aaron Himelstein.

The star was smoking hot and was not afraid to give lots of smooches to her man.

Leighton was wearing a multi-colored bikini having fun in the water.

The two lovebirds met and fell in love on the set of “Remember the Daze,” and the two seems to be still going strong.
