hollywood hat the roosevelt Chris Evans captain america

Our photogs caught up with Chris Evans as he stepped out with a new gal pal at Hollywood's Roosevelt Hotel Wednesday night.

Looks like he's her superhero; he held his ladyfriend's hand tightly through the parking garage in the sea of paparazzi. The two kept it casual, donning comfy clothes instead of club wear.

This mystery woman seems quite happy to be with Chris, 29, -- check out the hint of a smile she has in our gallery pics below!
