This is not OK.
Yes, we have some bittersweet news: Penn has a new girlfriend.
Domino just happens to be a musician herself AND sister to free-spirited Girls star Jemima Kirke!!!!
The good news is they're totally gorgeous and cool together, but the bad news is our dreamz of eventually becoming Penn's rebound have been crushed! *TEAR*
Maybe this means it wouldn't be impossible for Penn to guest star on Girls.
He would certainly be a VERY happy addition to the cast.
Anyway, congrats to the pretty new couple!!!
