Janet Jackson was allegedly seen cozying up to Colin Farrell

Could it be? No less a source than the venerable “Entertainment Tonight” celeb show reports that new dad Colin Farrell was pictured “warming up” to Michael Jackson’s talented baby sister Janet Jackson at the Beverly Hills Hotel last week.

An “ET” “special source” swears by the sighting, and there was a posting on the show’s Web site . . . but it’s kind of hard to believe.

The Irish actor just had a baby boy with his Polish actress girlfriend Alicja Bachleda Curus, so it’s doubtful that he’d chuck that good fortune at this point in time. 

Doubtful, but of course, when it comes to Hollywood, not impossible.
