Jessica Simpson is on the verge of marrying her American football star boyfriend Tony Romo, according to the sportsman's ex Sophia Bush. One Tree Hill star Bush is convinced the couple will wed in the near future. She says, "They're perfect for each other. They're both funny and wonderful and kind. I'm rooting for them." And Bush isn't the only person who thinks the Dallas Cowboys star will propose to Simpson soon - his rocker friend Michael Starr, who plays in popular Hollywood parody band Metal Skool and has been pals with Romo for years, agrees. Starr tells American magazine Us Weekly, "I think they're going to get married."
