2. Jennifer Lawrence and Nicholas Hoult
Before she was Katniss, Jennifer Lawrence played Mystique in X-Men: First Class, who sparked up a romance with Beast, portrayed by Nicholas Hoult. Like it so often does, this spilled over into their personal lives, and the two dated on and off for a few years before calling it quits during the filming for X-Men: Days of Future Past.
The two seemed to remain amicable post-split and were seen chatting at the Golden Globes in 2016. Both are scheduled to appear in the upcoming X-Men installment, Dark Phoenix, but given the scope of the film, it’s unknown whether they’ll be acting together this time around.
