None of this is confirmed yet, but we may have a new favorite celebrity couple. Page Six reports that Bill Murray threw himself a big party last night in New York to celebrate his new movie Rock The Kasbah, and the report refers to Jenny Lewis as Murray’s “current younger love interest.” This is, of course, a multiple-decade age gap between the mercurial movie star, 65, and the great singer-songwriter, 39. But this doesn’t seem so much like a typical Hollywood May/December relationship, mostly because it’s hard to imagine two people more fun to hang out with.

Page Six quotes a source who calls Lewis, the former child star and Rilo Kiley leader, Murray’s “special friend.” She apparently showed up late at last night’s celeb-heavy party, and her publicists won’t comment on the question of whether she and Murray are dating. She will, however, appear in Murray’s forthcoming Netflix special Very Murray Christmas and in a fake rock documentary to promote Rock The Kasbah. They have been seen together elsewhere:

Murray and his second wife Jennifer Butler divorced in 2008, when she accused him of domestic violence and being addicted to marijuana and alcohol. Lewis has most recently been linked with her Jenny And Johnny bandmate Johnathan Rice.
