Marlo Hampton just celebrated a birthday over the weekend and we were surprised to see one particular star from The Real Housewives of Atlanta acknowledging her special day on Twitter. Kenya Moore, of all people, took a moment to send Marlo a special birthday message.

"Happy Bday @iheartMarlo I wish u lots of love and happiness! Xo," Kenya wrote on her page.

Kenya attached a photo of her and Marlo — both looking fabulous! — in Manhattan. We're not sure when the picture was taken, but it looks like it could be fairly recent, maybe even from the current New York Fashion Week. The ladies certainly look dressed for it, with Marlo rocking a dominatrix-style jumpsuit with long black gloves, and Kenya looking picture-perfect in a kelly green, knee-length dress. Although, it's a little cold right now to be going without coats.

Considering how aggressive both Kenya and Marlo are and how similar their personalities seem to be, we have no doubt that the pair would cause massive blowups if they were consistently appearing on RHoA together — the same way Kenya and NeNe Leakes have clashed during Season 6 of the show so far.

And, yet, with Marlo only appearing as an occasional guest this season, Kenya and Marlo have somehow managed to hit it off and become fast friends.

When one of Kenya's followers asked her recently if she and Marlo are friends, Kenya replied that she thinks that Marlo is a cool girl. But based on her birthday shout-out, it sounds like Kenya and Marlo are closer than we first thought...
