Casper Smart, Jennifer Lopez’s boyfriend was angry at her for flirting with rapper and former boyfriend P. Diddy at her American Music Awards (AMA) 2015 after-party Sunday night, In Touch magazine reported Wednesday. However, another report claims that Lopez and Diddy were not flirting at all.

In Touch reported that Smart began “screaming at Lopez for “humiliating” in public by flirting with Diddy, according to Gossip Cop. “He [Smart] even accused her of still being obsessed with [Diddy] after all these years,” a source reportedly said.

However, the gossip debunking website stated that none of the claims in the In Touch were correct and source told them the report was “totally untrue.” According to Gossip Cop’s source, Diddy only “swung by quickly to say hello, and then left” and attended the part because a vodka band he promotes sponsored him. Lopez and Diddy are on friendly terms, the insider added.

Lopez, the 46-year-old host of AMA 2015, began her performance at the show singing one of her hits, "Waiting For Tonight," before addressing the crowd and telling everyone it was time to dance. She also told audience that AMAs was her favorite show and recalled performances and musicians she's watched over the years, including Whitney Houston and Michael Jackson.

"This show holds a very dear place in my heart," Lopez said. "They became like my heroes. I'm sure you loved them too... this show truly inspired me."
