Teen Mom’s Ryan claims Maci cheated on him with Kyle

Last week’s OK Magazine featured Teen Mom‘s Maci on the cover and with the tag line “How Maci’s trying to protect her son, Bentley, from her slimy ex Ryan.”

This week they’ve got Jennifer Aniston on the cover, but slimy ex Ryan has his own space in the upper left corner.

And he’s got ammunition against Maci, she allegedly cheated on him with Kyle King, the boy she’s currently dating, when she was still living with Ryan.

He alleges that when they were still living together, Maci confessed that she had an affair (with her current beau, Kyle King, 22) when Bentley was 4 months old.

“We were sitting in the living room and she just told me,” says Ryan, whose job as a diesel engine mechanic often took him away from home. “It probably happened when I was at work.”

Ryan also says in the mag that even though Maci’s with Kyle now she still calls trying to get back with him.

Shocking! If this is true, why hasn’t Ryan brought this up on the show? It would have helped his perception.

UPDATE: On October 6, 2010 US Weekly published a statement from Maci denying cheating allegations:

“He can say what he wants,” Bookout tells Us of the accusation. “I’m not going to pay attention to things that aren’t true.”
