Whilst Gwen has yet to address any possible 'tweakments', the platinum-blonde pop star previously opened up to The Telegraph about how she deals with society's ever-changing beauty standards.
"People talking about my aging is a compliment, I guess... I'm kind of obsessed with how I'm aging, too," she said.

Gwen added: "It's really hard for everyone to age and have to face life. Especially for females and people who have been in the spotlight. It can be daunting, but you tackle it by just trying to be the most beautiful version of yourself inside and out."
The singer's latest appearance comes after she spoke to Luisa via Roma's magazine about the power of makeup. Speaking candidly, she said: "You can always change who you are, make yourself feel better, or make other people feel better with makeup. Makeup is just the perfect playground for that."

I would collaborate with amazing makeup artists and try new things I never thought I could."
