Sabrina Carpenter betrayed? Olivia Dunne stirs the pot amid explosive Barry Keoghan cheating allegations

It looks as though Olivia Dunne has some thoughts on the recent reports that Sabrina Carpenter and Barry Keoghan are no longer an item.

The couple started romance rumors when they were spotted grabbing dinner together in Los Angeles during December 2023. This came after they first crossed paths during Paris Fashion Week where they both attended a Givenchy show the previous September.

Since then the two were very supportive of one another and their ventures. Keoghan regular posted on Carpenter's Instagram account and also appeared in her "Please Please Please" music video.

"I was like, 'Who's the greatest actor that I can find for this music video?' And he was next to me in a chair," Carpenter told CBS Sunday Morning. "And he was so excited about it."

However, a source told People earlier this week that the couple have decided to put their relationship on the shelf for the time being.

"They are both young and career-focused, so they've decided to take a break," the source told the outlet.

Dunne throwing shade?

While the source said the split was career-based, there are rumors around that internet that suggest Carpenter and Keoghan are over due to infidelity by the latter.

"It appears that this A-list singer who's having her breakout year and her foreign actor boyfriend are done for good," a source told gossip site Deuxmoi.

"On the closing night of her biggest tour to date in LA, he was busy getting very cozy at San Vicente Bungalows with a blonde, semi-famous, LA based influencer (who's particularly big on TikTok)."

What does Dunne has to do with all this? Well, the social media personality linked with Keoghan has beef with Dunne as they are well-documented rivals.

When rumors of the cheating broke on the internet and involved her rival, this brought some joy to Dunne who took a victory lap on TikTok.

"When her true colors are finally revealed in the national media," Dunne wrote over a TikTok video of her pumping her fist.
