Actress Courtney Cox has sparked rumours she is engaged to wed Snow Patrol rocker Johnny McDaid after she was photographed wearing what appeared to be an engagement ring on her wedding finger.
The Friends star has been dating the musician since late last year after their mutual pal Ed Sheeran introduced them, and McDaid has since moved into his girlfriend's Malibu, California mansion.
Now the couple appears to be really getting serious after Cox displayed a diamond ring on her left hand on Sunday as the pair made its way through Los Angeles International Airport to catch a flight to New York.
However, the actress had removed the ring as she and McDaid posed for pictures outside Manhattan's Ed Sullivan Theater on Monday, when she was interviewed on the Late Show with David Letterman.
Cox and McDaid have yet to address the rumours, and representatives for the actress had yet to respond to requests for a comment as WENN went to press.
If the couple is engaged, fans shouldn't be surprised - earlier this month, Sheeran said, "Things are moving fast. He moved in and, judging by the last time I saw them, they couldn't be happier. They get on really well and are genuinely good friends, pardon the pun."
When asked if the couple might marry soon, he added, "I wouldn't be surprised, but it's still early days. They certainly enjoy each other's company and feel very comfortable with each other."
Cox was previously married to her Scream co-star David Arquette, the father of her nine-year-old daughter Coco.
Arquette has also moved on following the couple's 2013 divorce - his entertainment reporter girlfriend, Christine McLarty, is pregnant with their first child together.
