Everything that's old is new again! Katy Perry, who recently collaborated with ex John Mayer on new track "Who You Love," was spotted reuniting with another old pal -- BFF Rihanna -- during an intimate dinner in NYC's West Village on Monday, Aug. 12.
The "Roar" singer, 28, looked glam in a patterned fur top as she posed for a snapshot with a newly shorn Rihanna that the "Diamonds" singer later posted to her Instagram.
"She. X She," Rihanna captioned the black-and-white shot, using hashtags "KatyAnna" and "RIHunited" to emphasize the besties' reunion.
"She joined the party of 15 upstairs but sat next to John and Katy to catch up," a source tells Us Weekly of Rihanna making an appearance at The Lion, where Perry and Mayer, 35, had been dining with pals.
It's been a while since the musical pals have been spotted together. The pair were last seen together at Rihanna's concert in Brooklyn at the Barclays Center on Tuesday, May 7, hanging out 'like old times" and "catching up," an eyewitness told Us of the friends at the time.
At the time, both pop stars had split from their men -- Rihanna from ex Chris Brown, and Perry from Mayer. On Monday, however, Perry and her former flame seemed to be back on track.
"She and John were adorable as Katy introduced him to people as her boyfriend and John affectionately held her close with his arm around her," the first source tells Us of the pair, who reconciled over Memorial Day weekend in May following a split in March.
Earlier that day, Perry chatted with the host on The Morning Mash Up live on SiriusXM Hits 1 about the couple's duet, and Perry hinted that the song might be a nod to their on-again, off-again relationship.
"I think that's just a love giggle," she said of the tiny laugh she contributes at the end of the track. "It's like the ones that Mariah Carey had in 1990 and stuff like that … Yeah, I think I was going for that, I think I was just so happy. I love that song…"
"It's very humanizing," she added. "It's like the real moment, you're catching the real moment there."
