A source - who allegedly laid witness to the adorbs date last week - told E! News: "It was very clear they are a couple and they were affectionate all night long. They had their arms wrapped around each other and he put his hand on her waist.
"They took pictures together with his phone and posed with their faces together."
Another source told E! that the new couple were hanging out until the wee hours of the morning.
"They came out [of Delilah] around 1:45 a.m. and stood rubbing each other's backs as they waited for their car. They never took their hands off of each other."
Luke and Ariel even hit the red carpet together on December 5th for the Lancôme x Vogue L'Absolu Ruby Holiday Event, so it all seems pretty official to us!
Ariel was previously dating actor Levi Meaden, but they broke up several months ago.
We love this new couple, now let's just make it Insta official guys!
