Khloé Kardashian and French Montana are officially back together.

The 'Keeping Up with the Kardashians' star, who split from the rapper in September after six months of dating, has reportedly told friends their relationship is back on track.

A source close to the 30-year-old beauty told E! News: ''Khloé and French are pretty much back on.''

Earlier this week, the reality TV star insisted she wasn't ''dating anybody,'' but admitted ''things could change'' and confessed: ''We all miss French. We love French. I'm still friends with him. I still talk to him everyday. I talked to him before I came here.''

The couple attended Diddy's 45th birthday party together in Los Angeles on Tuesday night (04.11.14), where they presented him with a new white Escalade.

The rapper shared a photograph of the generous gift on Instagram, with the caption: ''I HAVE A PEARL WHITE ESCALADE NOW!!! THANK YOU @frenchmontana @khloekardashian #DIDDYBDAYPARTY #DIDDYBDAYPARTYLIVE. (sic)''

French, 29, previously dismissed rumours Khloé's brother-in-law Kanye West set them up and revealed that Diddy, formerly known as Puff Daddy, introduced them.

The 'Don't Panic' hitmaker said: ''Everybody thinks that [Kanye set us up], it was Puff. Puff was the one that introduced us... It was a studio session that's where we met and I was like yo let me get her number and Puff gave it to me.''

Khloé originally broke up with French because he had grown too ''needy''.

A source said at the time: ''They are on a break. The relationship got too heavy and Khloé needed to take a step back.''

Another insider added: ''It grated on her that he became so dependent on her.''
