The former 'X Factor' judge and Newcastle United player had been together for six months but decided to call it a day after a series of rows.
Tulisa and Danny Simpson
The 24-year-old N-Dubz singer - who got a matching tattoo with her ex back in February - has since flown to Marbella in Spain on a girly break to help her get over the split.
A friend told The Sun: “Tulisa and Danny have been having problems for a while now and have been arguing a lot.They have been trying to work things out but Tulisa decided she’d had enough and didn’t want to fight for the relationship any more.
“It’s 100 per cent over. It’s an amicable split with no hard feelings.”
It's been a tough week for Tulisa. As well as her split from Danny, she also confirmed she's been axed from 'The X Factor' and replaced by Sharon Osbourne on the judging panel.
Taking to Twitter this week to confirm the news, she wrote: "Just wanted to let you all know that I won't be part of the X Factor panel this year.
"I've had a great time on the show, but this year it's time to do something different. I'd like to thank everyone on The X Factor for two amazing years. Stay tuned as I have a very exciting announcement soon!"
