Taylor Swift's new relationship has been sealed with a kiss!

The 22-year-old singer was caught kissing Conor Kennedy, the 18-year-old son of Robert Kennedy Jr. and the late Mary Kennedy, on Friday in Hyannis Port, Massachusetts.

In the steamy new photos, Conor sits on the ledge of a dock while holding Swift around the waist and sharing a smooch. Swift, wearing a black polka dot shirt, high-waisted red shorts and shades, wrapped her arms around her new boyfriend and kissed him back. The country cutie gave photographers a slight smile in a second snapshot while she held Conor's hand and he kissed her on the cheek.

A source confirmed to Us Weekly on August 1 that "Taylor is officially dating Conor Kennedy." Since then, the "We Are Never Ever Getting Back Together" singer has been photographed spending time with the whole Kennedy family on their compound.

Ethel Kennedy, Conor's grandmother, and Rory Kennedy, Conor's aunt, have already given Swift their stamp of approval. "She's a great friend of all of ours," Rory said during the Television Critics Association panel in Beverly Hills August 1. "She's awesome and we love her."

Can they see the "Love Story" singer becoming a Kennedy some day? "We should be so lucky!" Ethel said.
