Nadine Coyle is said to be one of the stars heading into the I'm A Celebrity jungle next week, swapping her showbiz life for the most gruelling reality TV show of all.
She burst onto our screens in 2002 when she took part in Popstars: The Rivals at the tender age of just 17.
But now, almost two decades later, Nadine, now 34, barely looks like she's changed at all with the same youthful glow and an ageless appearance that she had as a teenager.
While her reps deny she's had any cosmetic surgery or procedures, our expert takes a look at what she could have done to stay looking young.
A surgeon from MYA Cosmetic Surgery says: "I would suggest that Nadine may have undergone the non-surgical treatment of dermal fillers to her lips as she appears to have slightly fuller lips compared to previous images.
"The average cost of lip fillers in the UK can range depending on the provider and the amount of filler used, however, you can expect to pay anything from £200 to £1,000 per treatment.
"It is possible Nadine has had jawline and chin contouring with non-surgical dermal fillers. This treatment creates a more defined and slimming look to the chin and jawline and can cost around £150 to £300 per session, depending on the amount of product used.
"Weight loss can also affect a similar change of the face shape, but fillers will help create specific definition in this area.
"I would also suggest she has had the non-surgical treatment of dermal fillers to her cheeks. Fillers give volume to the cheek area and this is achieved by injecting dermal fillers along the contour of the cheekbone to create more definition. This treatment can typically cost in the region of £200 to £500 per session depending on the amount of product used."
In a statement to Mirror Online, the singer's rep said: "Nadine hasn't had any fillers whatsoever. If she had done she would simply be honest about it."
