Last year, Sean "Diddy" Combs, 49, and his longtime girlfriend Cassie Venture, 32, broke up - and it looked like the pair were finally over for good.

Cassie had moved on and began dating her personal trainer, Alex Fine. Cassie moved into Alex' home in Malibu, and the two were rumored to have been thinking about marriage.

But the pair split up last month, MTO News has confirmed. And this week, Cassie began seeing Diddy again.

According to one of Diddy's associates, he's been wining and dining Cassie for weeks - begging her to come back. And she finally came back.

The insider explained, "Diddy claims that he's changed and that this time he promises that he'll marry [Cassie]." We'll see if he keeps his promise.

And yes, we have receipts. First off, look at both Cassie's Instagram (here) and Alex Instagram (here). They both removed all photos of each other from the pages.

Next, look at the quality of Cassie's new weave - there's no way that Alex can afford that kind of hair. That weave got Diddy's money written all over it:

"Diddy won't ever let Cassie get away. He loves her so much," a source told E! News back in the summer of 2016 after Sean "Diddy" Combs and Casandra "Cassie" Ventura got back together in time for her 30th birthday party.

The duo first met in 2006, after Diddy heard Cassie's single "Me & U," which she had originally put out on MySpace, in a club and asked producer Ryan Leslie, who was working with her at the time, to produce her debut album for his Bad Boy Records.

Cassie dropped in August 2006 and debuted at No. 4 on the Billboard 200. When critics panned her promotional performances on TRL and BET's 106 & Park, Diddy threw his support behind the 19-year-old, calling her appearances "all right."
