Madonna and Sean Penn are setting romance rumours mills ablaze following a beachside meeting in Santa Monica, California.

The spotting comes after a slew of appearances from Sean Penn throughout Madonna’s recently wrapped American tour.

The exes were spotted enjoying drinks at the Shutters On The Beach Hotel, PageSix reports. And according to onlookers, the meeting was nothing more than a catch-up session. “They were both at the hotel, hanging at the bar area. They were just kicking it,” a witness revealed.

Penn and Madonna, who married in 1985, divorced 26 years ago citing irreconcilable differences. And it appears the pair has been able to maintain an ongoing friendship throughout the years. “I think he just really admires her work. They’re just really good friends and [I think] it’s sweet that they can have this relationship,” Penn’s daughter Dylan said recently about her father’s friendship with the icon.

“I did a show at Madison Square Garden the other night… and my ex-husband [Sean Penn] was there! Could you imagine?’ Madonna told the crowd at her Madison Square Garden show. “Thirty years earlier… he was very upset with me for wearing a costume that was too revealing. That’s not a lie! After the show, he wrote me a letter and said he finally appreciates my art.”
