Sean "Diddy" Combs is officially over Cassie Ventura - he replaced her with a younger Asian model. Diddy and Cassie - who is half-Asian - had been dating for the better part of  a decade.

But Cassie, 32, split with her wealthy sugar daddy last fall - and started dating her trainer.

For a while it seemed like Diddy, 49, would eventually get back together with Cassie and the two would get married.

Nope. Instead Diddy's dating a beautiful LA Asian model named Gina Huynh. The two had been romantically linked for years. Gina was allegedly Diddy's side chick for many years, while he was still with Cassie.

Diddy released video with Gina yesterday, the two were kissing and sucking tongues. He's now publicly proclaiming her as his new official girlfriend

Here are pics of his new bae:

If you look carefully on Gina's page, you can see that her wardrobe has gotten considerably more expensive in recent months . . . almost like she's just come into a lot of money.

Despite all this, "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."
