Age is but a number to Jamie Foxx.

The 47-year-old actor is reportedly being extra flirty with his 26-year-old co-star Lily James, which isn't being well received since the actress has a serious boyfriend.

“Jamie’s really into Lily. It’s clear she doesn’t enjoy his flirting, but he’s oblivious,” a source told the outlet.

Lily, who has been dating Dr. Who alum Matt Smith for over a year, is allegedly beginning to feel incredibly awkward whenever she's around Jamie.

“Lily’s a huge fan of Jamie, but his come-ons are becoming too much to handle. She’s hoping when they start shooting he’ll be more professional,” the source added.

Here's to hoping Jamie can take a hint and hit on someone who's not in a serious relationship!
