Jessica Simpson cancelled her 29th birthday party after being dumped the night before by her American football player boyfriend.
Jessica, who had called Tony Romo 'the love of my life' and spoke of wanting children with him, is said to be 'heartbroken' at the break-up.
She cancelled her Barbie And Ken themed celebration, writing on her Twitter page: 'Barbie party didn't happen, but I turned 29 and feel like I am on top of the world yelling I LOVE GETTING OLDER.'
'She is heartbroken, a source told U.S. magazine People. 'She loves Tony. But it's been difficult lately.
'He's busy with his career and she's getting ready to shoot her show (The Price Of Beauty). They decided to part ways.'
On the night of Jessica's birthday Dallas Cowboys player Romo was then spotted out partying, visiting Hollywood hotspot MyHouse with 14 friends.
'He had quite a few girls stop by his dance floor table,' another source told the site. 'Romo was sipping Grey Goose and having a fun time with the boys.'
Us Magazine also reported the split, citing a source as saying: 'It's been a long time coming.'
An additional source told the site that the couple could reunite at any time. 'They go from one fight right into another, without a second's break. It's always something with Jessica.'
The first source added that Simpson cancelled her birthday party because of the split, but is doing 'OK.'
Jessica had been dating Romo since November 2007. She was previously married to former boyband member Nick Lachey, with whom she starred in MTV reality show Newlyweds. Mail Online reported.
