The two apparently went public with their romance on Saturday night in New York City at a private dinner at Macao Trading Company.
An eyewitness tells the New York Post, "They turned up after midnight . . . they definitely looked like a couple."
They were there to celebrate Tatum Channing’s 30th birthday. Other guests included Tatum's wife, Jenna Dewan, Hayley Duff and her actor boyfriend, Nick Zano.
We totally see these two together. Josh has never been into the glam girls—some of his exes include Kirsten Dunst, Katie Holmes, and Mischa Barton.
Apparently Josh and Abbie were having fun together that night, since sources tell the Huffington Post they didn’t leave until the wee hours of Sunday morning!
