Mike Kline/ZUMA Press, Jeff Vespa/WireImage.comJessica Simpson didn't see it coming.
The 29-year-old singer was apparently blindsided by her birthday-eve breakup with Tony Romo.
"She was caught off guard," a source tells E! News of the sudden split.
In fact, as of last month, she was hoping to move in permanently with Tony in Dallas for the start of this fall's football season.
Looks like that won't be happening now. How's Tony been spending his newly single nights?
By partying with his boys.
On Friday, Jess' actual birthday, Tony and an entourage hit MyHouse, where he drank Grey Goose and chatted up women. Saturday, he spent the day partying poolside at the Roosevelt Hotel.
And just last night, Tony and his buds went to the Key Club in West Hollywood to watch '80s cover band Steel Panther perform.
The former couple once sang karaoke with the group back when they were together.
Jess has been lying low and spending time with family since the split.
