What is going on with Chris and Gwyneth?

Chris Martin got more than the he bargained for when the dirty boy (and we mean that literally because he is wearing a rather soiled sweatshirt) stopped by his local gas station on Tuesday night. Upon exiting the convenience store, our cameraman asked about the Coldplay front man about why he was hanging out with his estranged wife Gwyneth Paltrow on several occasions in the past week.

"We've gotta hang out," explained the 37-year-old Brit.

In response, our photog wished the singer a congratulations -- and Chris, not surprisingly, seemed a little confused by the well wishes. And then that's when things got a lil' awkward ...

Looks like we're all a little perplexed about what's going on with this consciously uncoupled twosome who can't stop spending time together!

Check out the video for the funny interaction!
