Christina Aguilera and her fiancé, Matthew Rutler, enjoyed a rare red carpet date night — complete with plenty of PDA.

Aguilera, 45, attended the Breakthrough Prize Ceremony in Los Angeles on Saturday, April 18, where she walked the red carpet with Rutler, 41, on her arm.

The pop star looked radiant in an off-the-shoulder black Salih Balta gown and wore her signature blonde tresses in a vintage-inspired bob. Rutler, for his part, opted for a classic black suit.

As Aguilera and Rutler posed on the carpet, he planted a kiss on her cheek for the cameras.

The couple have been together since 2010 and got engaged four years later, though haven’t been in a rush to tie the knot.

“There are no wedding plans at the moment. [Christina] and Matt are happy the way they are,” a source exclusively told Us Weekly in August 2022. “They’re one of those couples who don’t need a document to prove their love for each other.”

The “What a Girl Wants” singer and Rutler have also been busy raising their blended family. The pair share daughter Summer, 11, while Aguilera is also mom of son Max, 18, from a previous relationship.

According to Aguilera, her kids are already aware that their mom is a bona fide star.

“She’s so enraptured by the world behind the scenes and the production of everything, and she loves the band and the background singers,” the singer told Vogue in January 2024, referring to Summer. “She wants to take drum lessons — she is about it. She gives me so much love and support. Before I go on stage, she knows I get nervous, and she’s like, ‘You’re going to do great, mama.’”

Summer is even hoping to become her mom’s next manager.

“On the way to school the other day with her dad, [Summer] said, ‘When I grow up, I want to either be mama’s photographer or mama’s manager.’ It’s so funny,” Aguilera added at the time. “So we told will.i.am that [when he came to see my Las Vegas show], and he was like, ‘Oh, my God, she’s your daught-ager.’ So daught-ager is the word of the year. It’s just so cute.”

Aguilera, for her part, finds the combination of “daughter” and “manager” perfectly described Summer’s personality.

“If I’m running late for something or have an appointment, she’s like, ‘You know they’re waiting, Mama. We need to go,’” Aguilera explained to Vogue. “I was [previously] working with someone who predicted her birth to me, a very intuitive person, and she said, ‘You’re going to have a daughter, and she’s going to be your protector. She’s going to be on this earth to watch over you and protect and support you.’ And I’m like, ‘Oh, really?’ And literally she’s embodying that, and it’s just the most beautiful [thing].”
