Carmen Electra and Rob Patterson have confirmed their split.

The couple - who got engaged in 2008 - officially ended their relationship last month, with Rob moving out of Carmen's Beverly Hills home after becoming frustrated with some issues in their relationship, according to E! News.

However, it is believed the pair were having issues as far back as May.

Carmen was recently seen ''making out'' with Simon Cowell during a dinner date at Cecconi's restaurant in Hollywood, but friends insists the date came after her split with Rob.

A source said: ''They were getting very cosy. They were holding hands and staring into each other's eyes - and then they started making out.

''They were with other friends at the restaurant but didn't seem to mind.''

Carmen is said to be enjoying Simon's company, though their romance isn't serious yet.

The insider added: ''Carmen loves hanging out with Simon. They're having fun.

''She is getting back in the dating pool and Simon treats her very well. It's all very laid back at the moment but they are both enjoying themselves.''
