She's never made a secret of her desire to have bigger breasts.
And now Frankie Sandford has sparked speculation that she might have secretly gone under the knife to boost her cleavage, after showing off a curvier look on the beach in Los Angeles earlier this week.
Frankie, 23, displayed her apparently boosted cleavage in a green triangle bikini as she joined Mollie King and Vanessa White for a surfing lesson.
Fans were quick to comment on Frankie's change in appearance, with many speculating that she may have surgically altered her chest size.
And another fan wrote: 'When are people going to relise that when Frankie went missing from the group for a while that she had a boob job?
'She has always said she would like to have one, and they are visibly bigger.. #justsaying ;)'
However, others remarked that Frankie's noticeably curvier look could just be down to a well-constructed bikini top.
One fan wrote: 'Both Mollie and Frankie in the past have been quite open about being quite self concious of their small boobs so wear padding etc, 90% of bikinis have padding in them these days even for women who have big boob's so they've just gone and bought good bikinis.'
Another added: 'To all saying she has had a boob job, maybe the bikini top has a lift and some extra padding?
'I dunno something tells me if she would've had a boob job it would've been more obvious.'
And another fan of Frankie's said that at least if she has gone under the knife, she hasn't opted for ridiculously large implants, writing: 'At least there is an element of "has she or hasn't she" involved IF Frankie has been under the knife, nothing more ridiculous than beach ball implants!'
Frankie, who is dating footballer Wayne Bridge, spoke previously about her desire for a larger cleavage.
Asked what she disliked about her body, Frankie replied: 'I’m self-conscious of my bottom-half. I know I’m not large, but it’s something I think about. And I’d quite like bigger breasts.'
Bookmakers Paddy Power have now offered odds on whether or not Frankie will admit to having a breast enlargement this year, with odds of 6/4 that she will, and 1/2 that she won't.
