Are these X-Men
Although they split in January
, Jennifer Lawrence
and Nicholas Hoult were photographed arriving at the X-Men: Days of Future Past
private wrap party in Montreal, Canada on Saturday, looking more like a couple than former flames.
Lawrence, 23, and Hoult, 23, both star in the X-Men
sequel, but this isn't the first time they've been seen together since their breakup – in late April, they were spotted getting cozy
at a restaurant in Los Angeles.
Though they weren't openly affectionate, an onlooker said it "looked like a date."
The Oscar winner
and the Warm Bodies
actor met while both starring in 2011's X-Men: First Class
and dated for two years. Lawrence has said of Hoult
in the past, "[My boyfriend] is honestly my best friend, and hopefully I'm his best friend, too. He's my favorite person and he makes me laugh harder than anybody."
