Dannii Minogue sports a glamorous makeup look at the 49ers-Rams NFL game in Australia after surprising fans with her changing appearance

Dannii Minogue is one of the lucky sports fans to attend the San Francisco 49ers Vs LA Rams NFL game in Melbourne on Friday.

The pop star, 54, showed her support for the San Francisco side by wearing a 49ers scarf as she posed on the red carpet before kick-off.

Dannii swapped her usual glamorous ensembles for a sporty look, wearing a printed T-shirt, army pants and a bomber jacket.

But she certainly went glam with her hair and makeup, coiffing her brunette locks in a sleek blow wave and painting her face with a bronzed palette.

Her makeup accentuated her enhanced features after fans speculated whether or not Dannii had recently had Botox or filler.

Last week, Dannii looked almost unrecognisable as she was spotted out and about in Melbourne with her brother Brendan and father Ron.

Completely makeup-free, her complexion looked slightly puffy as she rugged up against the cold weather.

This week, Dominika Gialouris, the co-founder of Body Sculpting Clinics, shared her expert opinion on the Australian icon’s new look.

'Looking back at earlier photographs, Dannii's lips appear fuller over time, although differences in expression and camera angle make direct comparisons difficult,' Dominika told the Daily Mail.

'That alone doesn't establish whether she has had dermal fillers, and I have no knowledge of her treatment history. What stands out is her skin.

'It appears smooth and even toned, even in the candid photograph. She looks like someone who takes great care of her skin and appearance. Dannii looks stunning.'

Dominika went on to say that while Dannii's countenance appeared 'fuller', there was no reason to 'automatically attribute that to filler'.

'The contours beneath her eyes and across her upper cheeks look fuller just in that photograph, but I wouldn't automatically attribute that to filler,' she said.

'Lighting, angle and expression can all influence how those areas look, and it's difficult to tell from just a photograph alone.'

Dannii's new look divided followers last week, with some speculating that she may have had some work done recently, while others said she 'looks fabulous'.

'Botoxed and filled too much,' one person said, adding that 'less is more' as they advised that the singer should 'keep it natural as much as you can with these treatments'.

'If I could only afford all the Botox and fillers she has had!' another said.

'Allergies or fillers?' a third noted, while someone else commented: 'Full of Botox and fillers.'

Meanwhile, other fans said Dannii 'looks the same' as usual, adding that she is 'fabulous'.

'She looks fine. What’s the issue?' one person wrote, as another commented: 'She looks the same.'

'Her skin looks great and I get it, I wake up with piggy eyes some mornings too,' a third noted.

'She looks fabulous. What are you talking about?' yet another noted.

The 49ers have spent the last week in Australia preparing to face the Los Angeles Rams, a game that is actually taking place on Friday morning local time and airing in the US on Thursday evening.

The two teams are playing at the Melbourne Cricket Ground in their Week 1 matchup.
