Tony Romo gives Jessica Simpson ultimatum!

That's the ultimatum Dallas Cowboys quarterback Tony Romo gave girlfriend Jessica Simpson a wake up call after the 28-year-old beauty went on a post-tour party spree.In late March, the Texas-bred blonde wrapped up her tour opening for country music titans Rascal Flatts, and she's been celebrating by cutting loose with a series of alcohol-fueled nights out, say sources.

"Tony is fed up," the insider says. "She's been pressuring him to marry her and have children, but he's giving her a firm 'no' until she cleans up her act." With her career at a standstill, Jess has shifted her focus to convincing Tony that the time's right to get married and start a family. "But Tony won't even consider moving forward with Jess until she cuts back on partying,"

Is this the Jess we all know and love? Tony told his family "I'll give her one month, if she doesn't change it's over."
