Christina Aguilera opted for a striking angelic look as she stepped out at the Breakthrough Awards on Sunday in a long, white corseted dress.

The Genie in a Bottle singer, 44, showed off her enviable waist in the long dress, which featured an unusual corseted design.

Wearing her hair in waves, it was pulled back from her face by a half up-do that accentuated the singer's earthy choice of makeup. 

She opted for a simple French manicure, revealed when she put her hands on her waist. 

The entire look was brought together by a selection of silver jewellery, which made Christina's dark choice of lip really pop. 

Christina was not alone at the event and was joined by long-term partner and fiancé, Matthew Rutler, 40. 

The couple, who have been together since 2014 and share a daughter, Summer Rain, did not hold back with the PDA on the red carpet.

They were pictured in several snaps sharing a passionate kiss.  

While the pair have been engaged now for over a decade, Christina previously said that they were in no rush to get married.

The Dirty singer told PEOPLE in 2015: 'Having just moved into a beautiful new home we call "the Sanctuary", having a baby, and now being so excited to get back to work, I have my hands full, and am not in a rush to set a date.

'I want to plan it and cherish the moment, while not feeling rushed.'

The happy couple met in 2010 on the set of Burlesque, where Matthew was working as a production assistant. 

The singer said: 'Matthew is a special person. We had a really strong friendship on the movie. 

'He’s the kind of person you could spend hours on the phone talking to and all of a sudden it’s daylight.'

Christina was previously married to actor Jordan Bratman between 2005 and 2011. 

The former couple had one child, Max Liron, now 17, who they have chosen to keep largely out of the spotlight. 

As Christina's personal life goes from strength to strength, she is continuing with her Las Vegas residency in 2025.

The singer is also working on a new album, the details of which are currently under wraps. 

She told PAPER magazine in 2024: 'Music is dying to come out of me. At this point, there is a new me that has been growing and building, and it is so ready to emerge. 

'It’s going to take a little longer than I wanted it to, but it is what it is.

'I definitely need a moment to be left alone, to make my art and come up with what I have to say. 

'But I have so many lyrics at this point. I have so many thoughts and feelings, and I’m a different person than I was even last year.'
