Chris Evans was spotted grabbing lunch with his Opposite Sex costar Lindsay McKeon last week, sparking dating rumors.

Chris Evans, Lindsey McKeon Dating?

Evans and McKeon dined out at Hollywood’s El Compadre restaurant, leaving with a bag of leftovers. The Captain America star looked buff and ready for filming more franchise sequels in a maroon Henley and gray jeans. McKeon, meanwhile, donned black leggings and a leather jacket for the outing.

While the two look as though no time has passed since their 2000 movie together, it’s unlikely that a romance is brewing. McKeon is actually off the market and has been married to Brant Hively since 2013.

“They’ve worked together. She’s married,” a source told Us Weekly. “Just a friendly catch-up. He’s still single for the most part.”

Evans was last linked to Friday Night Lights actress Minka Kelly. He also dated Jessica Biel before she settled down with now-husband Justin Timberlake.
