Is Amanda Channing's other woman?

Amanda Bynes has got the Chad Michael Murray syndrome. She’s begun dating her She’s the Man co-star, Channing Tatum. The only thing is, Tatum is dating someone else as well, reports Star magazine.

Channing’s dad, Glenn filled Star in on his son’s love life. "Channing has been in a committed relationship with another young lady, also an actor, for about six months. She's been in Japan working for the past three weeks, but they've been in touch nearly every day she's been gone."

Bynes must not know about this other woman as she was seen getting very close with Tatum in NYC recently. A witness to their PDA said, "They were all over each other and shared a deep, passionate kiss. They were very lovey-dovey."

Glenn, meanwhile, discredits the kiss and says that Channing and Amanda are just friends. "Friendships were formed [during filming], and many of these people have stayed in touch, including Chan and Amanda."
