Matt Smith and Richard Madden's kissing selfie should make Jenna Coleman jealous

Jenna-Louise Coleman had better watch out, because someone's going after her man. What's even crazier is she knows that someone rather well after sharing a TARDIS with him.

Former "Game of Thrones" star Richard Madden, who has been in a relationship with Coleman since 2011, posted a selfie on his Instagram with none other than "Doctor Who" star Matt Smith. In the photo, Smith is planting a nice, big kiss on Maddens cheek. "Kiss me quick #summerlovin," he captions the show.

Does Coleman have some competition for Madden's heart? It can't be easy to turn down a Doctor. After all, he's got the coolest mode of transportation in all of space and time. What beats that?
