Britney Spears was "so nervous" ahead of her sons' runway debut.

The Toxic singer wasn't in attendance to see Preston, 20, and 19-year-old Jayden - who she has with ex-husband Kevin Federline - walk in the Vetements menswear Spring/Summer 2027 show at Paris Men's Fashion Week last week, but she made sure they knew she was thinking of them and they had her full support.

Speaking to America's Vogue magazine, Jayden said when asked Britney's opinion: "Oh my god, she was so nervous for us. She was just looking out for us and making sure that this was what we wanted to do.

"She wasn't there with us, but she sent us flowers to our hotel as a good luck thing, and called and texted us so many times. It was good to have that and to carry that with us before we went out there."

But Britney had every confidence in her sons.

Asked if she'd offered any advice, Jayden added: "I feel like she knew we had it. She was like, 'Yeah, you guys are my sons. You've got this.' "

The brothers were thankful they made their debut together.

Jayden said: "Right before we were about to walk out, I remember Preston and I just looking at each other and nodding our heads, because we weren't close enough to give each other a pep talk.

"I would've been really, really messed up if Preston wasn't doing it with me."

Although Preston and Jayden had a great time on the runway and are open to more modelling opportunities, their ultimate shared passion is making music.

Jayden said: "I don't know about Preston, but I'm definitely interested. I feel like I could do better, since this was my first fashion show and everything. I could master my walk better--I was definitely stiff because I was nervous. But Preston and I are trying to do music and other things."

Preston added: "After being in that environment, I love it so much--seeing how a whole show is put together. But I don't know if it's something that I would pursue or not. I don't know if it's something that I'm super passionate about, but I know I had a lot of fun doing it.

"Music is the foundation of everything for me. Jayden and I have done music our whole lives, and we definitely gravitate towards that more than anything else."
