Tony Romo Gambles Like He's Still In Charleston, Ill.

Want to know the perils of being a "superstar" Dallas Cowboys quarterback who tends to have some trouble getting his team out of the first round of playoffs? If you start dating a featherbrained "pop star," you might end up in Robin Leach's blog — Robin Leach's blog! — with stories about losing $2.5 million in Vegas.

Yes, according to Robin Leach — who's yelling and he DOESN'T KNOW WHY — Tony Romo dropped a considerable bundle in Vegas and upset poor little Jessica Simpson. An excerpt:

It began when Jessica, Tony and the players all hit the Peacock Lounge for high limit blackjack. Jessica was said to have won $5,000 and then they retired to their penthouse while the others went onto the Body English nightclub. The couple even spent some time tanning in the sunshine rays at the new $8 million makeover pool at the Hard Rock while watching the NFL draft on their private cabana HD TV screens. At some point, however, allegedly Tony, who was rumored to be paid a $15,000 appearance fee at Body English took the money and went gambling. My spywitnesses tell me that by the time he was finished he'd lost a fortune and I swear to you I was told that the figure could have run as high as a whopping $2.5 million. Whatever the staggering loss totaled it immediately put a damper on their fun weekend. I'm reliably told Hard Rock officials offered to pay Jessica a bonus $25,000 if she'd co-host at Body English the second night with Tony. Allegedly a livid Jessica refused because she's paid far more for personal appearances and the fun weekend had suddenly turned into a commercial gig. Also she was said to be "angry beyond words" over his gambling and the large loss. Insiders told me that one thing led to another and they wound up in a "furious fight."

It's worth noting that Romo just signed a new deal last year, and hey, good thing! Otherwise, Simpson's gonna have to start charging even more for personal appearances.
