We compiled a list of all his romantic encounters through the years, which include his newest ex, Shayna Taylor, with whom he split just before his 40th birthday.

Seacrest, who has hosted Dick Clark's Rockin' New Year's Eve the past ten years, addressed Mariah Carey's botched outing on the annual special on his radio show, On Air With Ryan Seacrest, Thursday.

He kept diplomatic while defending Dick Clark Productions, who Carey blamed the catastrophic outing on, citing technical gaffes.'She knows what Times Square’s about,' he said.

When asked about his apparently single relationship status, he quipped: 'Well, how do you know I don't have a date here?

The radio DJ and television producer/personality, 42, was snapped shopping at Barneys New York in Beverly Hills, California with Shayna Taylor, a breathtaking model he was previously linked with in 20.

The angel-faced model, who was once signed to the famed Wilhelmina agency, had her dark blonde locks pulled back in a bun.

The wealthy bachelor has previously been linked to actresses Teri Hatcher and Sophie Monk; and was involved for nearly three years with Dancing With The Stars beauty Julianne Hough, until the pair split in March of 2013.

Ryan took her as his date to Guess co-founder Paul Marciano's wedding in Bora Bora over the Thanksgiving weekend.

And they were spotted enjoying a day on their bikes in the ocean-side neighbourhood of Venice in Los Angeles in early December.
