The Saturdays' Frankie's £40,000 Engagement Ring From Wayne Bridge

Wayne Bridge has reportedly bought The Saturdays' Frankie an engagement ring worth £40,000.

Wayne popped to posh jewellers Graff Diamonds in London where he picked up a 3.5-carat canary yellow diamond for The Saturdays' Frankie Sandford.

Four of the five Saturdays are in serious relationships, but it's thought Frankie will be the first to be engaged as Wayne told friends he's just waiting for the "perfect moment" to pop the question, say The Sun.

"He's got his heart set on asking her in the run up to Christmas," a source said recently.

"He's 100% besotted with Frankie."

Frankie, who has ditched her cropped hair for a slightly longer style, has been dating Wayne for the last nine months since splitting from her McFly boyfriend Dougie Poynter.

The Saturdays are preparing for their UK tour later this year, which comes just after the news that Frankie's bandmate Una is pregnant, but the girls are all still fully committed to their 'All Fired Up' gigs.
