This Morning viewers were left seriously concerned as US singer Christina Aguilera appeared on the show on Tuesday.

Christina, 44, joined Alison for a pre-recorded interview during the latest instalment of the show as Dermot O’Leary, 52, and Alison, 50, hosted the daytime hit.

It comes as Burlesque arrives on the West End, 15 years after the iconic movie hit screens in 2010, with it marking Christina’s film debut.

Burlesque The Musical is now playing at the Savoy Theatre for a strictly limited season until 6 September 2025 following its sold-out run in Manchester.

Genie In A Bottle hitmaker Christina wore an olive coloured corset-style bodice for her chat with Alison as she showed off her slim figure, while boasting a large bust.

However, as the Birmingham native interviewed the Grammy Award-winning singer-songwriter, fans watching at home were distracted by her appearance.

Posting on X, formerly Twitter, one viewer said: ‘My God what has happened to Christina, is that even her?’

A second harshly commented: ‘State of Christina. Really sad to see… Britney is having a meltdown too.’

‘Is Christina Aguilera ok? She doesn’t look well,’ asked a third worried fan.

While a fourth remarked: ‘She’s wasting away.’

Christina previously displayed her thin appearance and caused panic among fans, who discussed rumours she might have undergone plastic surgery on her face to achieve her transformed appearance.

Her frame has also sparked rumours about whether may have turned to Ozempic-like drugs to bring about her drastic weight loss.

Despite the speculation among fans that she may have altered her appearance in some way, the Grammy-winning singer–songwriter has not addressed the comments.
