Tony Romo Cheated on Jessica Simpson

Tony Romo dumped Jessica Simpson the night before her birthday July 10.

But was the Dallas Cowboys quarterback hitting another receiver deep (if you know what we mean) prior to that? That's what new reports are insinuating.

Jessica Simpson exuberantly announced "the man who loves [her]" was at a February 6 concert - seemingly not concerned about Tony Romo was sitting with Natalie Smith, a younger, skinnier look-alike of the alleged singer and actress.

And that's not all. According to Us, Tony Romo had been sending "flirty texts" to Natalie Smith for months while still putting up with Jessica Simpson.

After the show, Tony Romo introduced Simpson to Smith, 22, the daughter of the athletic director at Romo's alma mater, Eastern Illinois University.

"We hung out for, like 10 to 15 minutes, backstage," said Natalie Smith(pictured left) according to the celebrity gossip tabloid. "She was cool and nice."

But multiple sources says Simpson should have been suspicious, as Romo had an "emotional affair" with Natalie Smith months before dumping Jessica.

"They are not officially dating, but are having an intimate relationship," a Smith source says. Adds another pal of Smith, who typically dined with Romo when he'd visit his college town: "They've always flirted and texted each other."

"They had phone conversations one to two months before the breakup."

It gets better. While Simpson is a "wreck" over the news, Natalie Smith is supposedly "determined not to become clingy like Jessica." Good call, Nat!  Posted By: .xoxoSOURCE
