Now, they've confirmed the rumours by kissing in public.
In new pics, the couple can be seen doing some major PDA while walking the streets of New York together.
And it didn't even end there! Once inside a restaurant, Timothee was spotted stroking Lily's hair and kissing her some more.
If they aren't the most on-brand, millennial couple of all time, we don't know who is.
After the couple were spotted together, a source told Us Weekly, “They were walking down the street, and he stopped her and pulled her close. They started making out for a while, for over a minute.”
