Taylor Swift is getting the stamp of approval from her boyfriend Conor Kennedy’s family, and his cousin says she’s helping him deal with the tragic suicide of his mother.

The 22-year-old You Belong With Me singer has been defending her relationship with her younger 18-year-old boyfriend, but most of his family seems to be completely enamored with the singer dating the high school student, including his own sister.

Kathleen “Kick” Kennedy, Conor’s half sister (they have the same dad, Robert F. Kennedy Jr.; she has a different mom, Emily Black) said she’s supporting him with his very public romance with the Grammy award winning singer.

“Whatever makes Conor happy makes me happy,” Kick, 24, told New York Magazine about Taylor’s relationship with her 18-year-old brother in an interview where she opened up about being part of the famous Kennedy family and her own acting pursuits.
