Los Angeles: Actor Michael Sheen is reportedly dating VH1 `Morning Buzz` host Carrie Keagan after splitting with Rachel McAdams earlier this year.
The new pair, who have just begun their romance, are largely keeping quiet about their relationship, reported Us magazine.
"She really likes him. Keegan was by her new man`s side at the `Master of Sex` premiere after party, held at the Morgan Library and Museum in NYC September 26. She was all over Michael like a smitten schoolgirl!," a source said.
Sheen, 44, previously dated his `Midnight in Paris` costar McAdams for a little over two years before the two called it quits in February.
Keagan was earlier linked to `The Social Network` director Aaron Sorkin after they spotted together at the Golden Globe Awards.
