Are Jennifer Lawrence and Nicholas Hoult together again? The ex-couple have been frequently spotted hanging out with each other lately. Yes, it must be because they're filming the X-Men movie sequel, Days of Future Past, but is that all there is to it?

They were seen going for a walk with Nicholas' brother and nephew; they went to dinner, just the two of them, in Montreal and LA; and last they were seen was at the Montreal, Canada racetrack when they visited the Canadian Grand Prix Team, according to reports by the Daily Mail. Are they back on?

Both actors have not released a statement amid the speculations, all that people know is that they have remained cordial toward each other despite the break up in January. Jennifer even described her ex-boyfriend as her "favourite person to be around" and her "best friend." And Nicholas returned the sweetness by wishing Jennifer well as she went on an award-season rampage culminating in her Oscar win in March.

Now that they're always together due to work, have they realised a few things about themselves? Like maybe Nicholas realised how awesome Jennifer is. Or would he just really want to be BFFs with her? If it's the latter, then Jennifer - the loveable, girl-next-door, funny person that she is - deserves to be happy and should be out dating again soon. When time comes that she's ready, here are some names that we think can be suitable candidates to become the future Mr. Right for America's favourite sweetheart (well, supposing they're all singles!). Take your pick.

The Perfect Leading Man Bradley Cooper - He and Jennifer are constant work mates, having starred together in the film Silver Linings Playbook (where Jennifer won an Oscar trophy), and are now working on movies American Hustle and Serena.

The Perfect Gentleman Joseph Gordon Levitt - His gentlemanly looks and ways would put Jen in a nice place. They would look good together, whether out on a date or out on the big screen. Agree?

The Pitch Perfect Skylar Austin - Like Jennifer, he seems warm and friendly. He's kept close ties with his Pitch Perfect co-stars even after the movie. And oh, he rocks the fedora too like JLaw.

The Perfect Brit Ed Westwick - Since Jen has been with a Brit before (Nicholas Hoult) why should it surprise if she went for another Brit again? They're hot like that.

The Perfect Male Counterpart Dylan O'Brien - This Teen Wolf hottie has been branded as the male JLaw. So why not make it official, then?

Now, who's your pick?
