Superproducer Mark Ronson has further sparked rumors that his younger sister, celebrity DJ Samantha Ronson, is dating actress Lindsay Lohan after calling the pair “a cute couple” on the pages of a British tabloid this week.

‘My sister and Lindsay make a cute couple, don’t they?’ Mark, thirty-two, told the Sunday Mirror.

Neither Lindsay or Samantha have confirmed widespread rumors that they are booty buddies, but the girls were snapped in a passionate embrace on the Los Angeles set of Lindsay’s new film, Labor Pains, on Monday.
