Pop singer Jessica Simpson and American Football star Tony Romo reportedly parted ways on the eve of her birthday.

“She loves Tony. But it’s been difficult lately,” Fox News quoted a source close to the singer as saying.

“He’s busy with his career and she’s getting ready to shoot her show ‘The Price of Beauty.’ They decided to part ways,” the source added.

Meanwhile, the Dallas Cowboys quarter back was spotted partying with a group of friends at Hollywood club ‘MyHouse’ instead of spending time with the singer on her birthday.

However, Simpson’s reps have refused to comment on the matter.
