Just last night, the Ivy League-educated actor was a surprise performer at Campari's 150th birthday bash at the Bowery Hotel.
And not only did he sing for all the partygoers, but he did a duet with drag performer Kalup Linzy!
"He wanted it to be kept hush-hush," a source tells me of his show.
So what did he sing?
"He was singing lines like, 'Gimme ass,'" a source says, adding that James also belted out "Proud Mary."
So he sings, he acts and he's college-educated—what's not to love about this guy?
See who else was out and about in Party Pics: New York!
