Kylie Jenner fans think she got a ‘BUTT lift’ as star’s backside looks much bigger in recent years

One wrote: "It's honestly embarrassing that she denies so much work and makes up silly excuses."

Another referred to the plastic surgery Kylie's sisters are rumored to have had, saying: "All of their BBLs look so ridiculous."

"Oh I knew that ass was fake!! Lol," a third posted.

Kylie has never commented on endless speculation over her changing body and newfound curves.

She did, however, admit in 2015 to getting lip fillers after dealing with insecurities about her "small lips" since she was a teenager.

She previously said: "I was 15 and I was insecure about my lips.

"I had really small lips, and it was, like, one of my first kisses, and a guy was like, 'I didn't think you'd be a good kisser because you have such small lips.'

"I took that really hard. Just when a guy you like says that... I don't know, it just really affected me. I didn't feel desirable or pretty.

"I would overline my lips with the lip liner to create the illusion of bigger lips and then, finally, I was like, this lip liner isn't doing it and ended up getting my lips done. It sticks with you - it just got in there."

Rumors that she'd had lip fillers were sparked in 2014, but the Kylie Cosmetics founder initially brushed over the speculation.

LIP FILLERS

She finally addressed it on KUWTK in 2015 when she was 17, saying: "I have temporary lip fillers.

"It's just an insecurity of mine and it's what I wanted to do. Everyone always picks us apart.

"I want to admit to the lips, but people are so quick to judge me on everything, so I might have tiptoed around the truth, but I didn't lie."

Meanwhile, the reality star has been keeping busy in recent weeks looking after her second child, Wolf, with baby daddy Travis Scott.

The couple has yet to share any photos or videos of their son, except for one of him holding his big sister's hand.

However, Kris opened up about Kylie's second birth recently while guest-starring on The Ellen Show.

PROUD GRANDMOTHER

She gushed: "He's so cute. It's amazing I was in the hospital when he was born. It was me, Kylie, and Travis.

"Because they have rules and regulations now so you can only have so many people."

She continued: "Back in the day I had like 15 people when I was giving birth it was like a party, but now it's very controlled.

"And when he came out, it was like 'there's Stormi being born all over again.'"
