The 32-year-old slipped a huge yellow diamond sparkler designed by Jacob Arabo on her wedding finger at the Palladium Jewellery launch in New York.
And she would certainly be a beautiful bride.
Hint hint! Stacy Keibler tried a yellow diamond engagement ring on for size at the The Palladium Jewelry By Jacob & Co. Launch Celebration hosted by W Magazine held At Jacob & Co
She tried on the gem at the bash as she stepped out in a striking white Marchesa dress.
Her rather unsubtle marriage hint comes after just days after Clooney vehemently denied the pair had split.
The actor's representative quashed the rumour quickly and decisively.
'A story published by a London tabloid, The Sun, concerning George Clooney and Stacy Keibler is not true. Total fabrication designed to sell newspapers,' the actor's PR representative Stan Rosenfield told the Mail Online.

They alleged that Stacy had told friends that her relationship with the 51-year-old actor was over due to his unwillingness to commit.
According to the publication, George had apparently told the stunning WWE wrestler that he wanted to be on his own again.
'She said George wants to be on his own again and has no intention of getting married,' a source was alleged to have told The Sun.

The actor first took Stacy there in June, and the pair have barely left the idyllic spot ever since.
During their sojourn they also caught up with numerous friends, as well as George's parents Nina and Nick.
And on the 25th of July, George and Stacy were spotted having lunch with both his parents and her own parents, Patricia and Gary.
The couple first started dating in August 2011, a month after he split from his long-term girlfriend, Italian model and actress Elisabetta Canalis,
According to U.S. reports at the time, the Ocean's Thirteen actor had been quietly dating the statuesque blonde for some time, after having known her for several years.
One insider told American magazine Us Weekly at the time: 'It's more than just a fling. They're basically exclusive at this point. They like each other's sense of humour.
'Obviously they're both physically attracted to one another.'
Clooney split from Canalis in July 2011 after she had dropped hints in interviews that she was keen to marry and have children.
At the time they released a joint statement confirming the end of their two-year relationship, saying: 'We are not together anymore...It's very difficult and very personal and we hope everyone can respect our privacy.'
George was married to New York actress Talia Balsam for four years between 1989 before divorcing in 1993.
Talia currently plays Mona Sterling on hit U.S. show Mad Men, playing the ex-wife of her real-life husband John Slattery, who plays ad man Roger Sterling. The couple have been married since 1998 and have one child together.
In an interview in early 2011 with Piers Morgan, George said he had no plans to marry again.
He said: 'I hate to blow your whole news story, but I was married,' George said in the interview on CNN's Piers Morgan Tonight.
It came after he was asked by his father Nick (who appeared alongside the actor) about considering marriage.
He added: 'Yeah, so I’ve proven how good I was at it, and I just. … I’m allowed one.'
