Whitmore and Nutini fuel rumours as they share drinks on Dublin visit
However, it was the timing of her return trip and visit to Dublin's Olympia Theatre that set tongues wagging.
The 28-year-old was in the capital at the same time as her rumoured boyfriend, Scottish singer Paolo Nutini, who performed two gigs at the Olympia on Thursday and Friday.
Bray native Whitmore touched down in Dublin on Saturday after a long-haul flight from Canada and headed straight to the city centre venue.
The blonde, who was in a long-term relationship with Coronas frontman Danny O'Reilly until 2012 before rekindling their flame briefly last year, was pictured next to a Glen Hansard photo frame in the Olympia on Saturday night.
Nutini, who had a day off from his tour schedule, stayed around the capital on Saturday. He is said to have had drinks with the presenter and her close friend, Eoghan McDermott.
Whitmore flew back from attending Vancouver Fashion Week a day before she was scheduled to appear on McDermott's Voice of Ireland Afterparty show.
The I'm A Celebrity Get Me Out of Here Now host is rumoured to be in a relationship with Nutini after the pair were seen attending a number of high-profile events together.
Whitmore is rumoured to be seeing crooner Nutini
Since her split from O'Reilly, she has been linked with a string of eligible bachelors.
Earlier this month she posed for photos with underwear model David Gandy, who she dated in 2010.
They were believed to have re-kindled their romance last year, but are now just friends.
She has also been linked with musician Miles Kane and was seen cuddling and holding hands with him at the Electric Picnic festival in Co Laois last summer.
Nutini is notoriously private when it comes to his love life and was less than impressed when quizzed over his romance with Whitmore.
Refusing to deny the rumours, the 27-year-old said "its none of your business" when asked if he was dating the presenter by Today FM host Ray D'Arcy.
