The stars of X-Men: First Class rolled up to their premiere at NYC's Ziegfeld Theatre last night in a collection of vintage cars, perfect for the blockbuster set back in the '60s. Leading men Michael Fassbender and James McAvoy were dapper on the carpet following a long day of work at their press junket — stay tuned next week for our chat with the guys! January Jones covered up her baby bump in a blue and black Preen dress while Zoe Kravitz supported her longtime pal Alexander Wang in a gray velvet maxi. The cast was rounded out by Rose Byrne, Lucas Till, and Kevin Bacon, who fit a stop by The Late Show between afternoon interviews at the evening's screening. Rumored couple Zoe Kravitz and Michael Fassbender kept their distance on the carpet, posting with their many costars in between. The movie actually brought together another duo, since Jennifer Lawrence and Nicholas Hoult are apparently dating now, too! Jennifer and Nicholas, though, weren't able to attend yesterday's event. The X-Men family connections keep coming, with Zoe's dad Lenny now set to star in The Hunger Games with Jennifer.
