In related news, Miss Simpson recently sparked rumors that she’ll be moving in with boyfriend Tony Romo, after reportedly “swapping her hotel room to stay with the football star during a recent visit to her home state.”

A source tells the Us Weekly, “They are doing great. Now it’s Tony, Jess and his roommate!” Meanwhile, another insider adds, “Jessica stays at his home when she’s in town, but she hasn’t totally moved in yet. She’s been busy with her country music stuff. …

On Wednesday’s Ellen, recorded on Monday, Jessica says Ashlee Simpson-Wentz has been doing “different foot massages and stuff” in hopes of provoking labor.

As for the previous evening, Miss Simpson was busy singing for the thousands of fans attending the State Fair of Texas – including her quarterback boyfriend Tony Romo.
