Not to mention, they were affectionately strolling hand in hand following their meal as well.
The Avatar star was first rumored to be dating the stunning model when they attended the Cotton On Foundation's Global Citzen Concert in New York City last month that was headlined by Bono, Kings Of Leon, Stevie Wonder and Alicia Keys.
Worthington was last linked to Sophie Monk earlier this year when she picked him up from a Melbourne airport.
The 37-year-old actor held the model's hand as they walked through the airport together, but kept their PDA to a minimum.
However, Monk laughed off rumors they were a couple, telling Express news, "We're very close but we're not dating. He's a good friend. I really like him. He's just really down to earth and really Australian."
