Kourtney Kardashian is planning to go under the knife for Justin Bieber, according to a Life & Style magazine report cited by Hollywood Life. Kardashian and Bieber are reported to have been in an on-again, off-again relationship amid the Canadian singer’s alleged romance rumors.

“She wants to hold onto Justin,” a source close to Kardashian told Life & Style. “With all the models half her age that Justin has been with, Kourtney is feeling insecure. She’s been working super hard on her body and she looks amazing, but she feels like she could look much younger.”

Bieber reportedly began dating Kardashian because he considers older women to be “dominant,” while the reality TV star was involved with him in a bid to annoy her former partner Scott Disick. However, the two parted ways after some time and have been linked often since then.

The insider also told the magazine that the 37-year-old “thinks that her weight loss has caused some sagging skin around her neck and jawline.”

“She also thinks she looks tired. She’s not quite ready for a face-life yet, but she’s considering a neck lift and a forehead lift, which will help her look 10 years younger,” the source told Life & Style.

However, the magazine’s report is unlikely to be true. Gossip Cop reported citing a source that Kardashian does not plan to undergo plastic surgery and would not change herself for any man.

Meanwhile, Bieber was also recently rumored to have gotten back with his ex-girlfriend Selena Gomez after she attended his concert in Los Angeles last month. The two were reported to have spent time together at a hotel in Beverly Hills.

Gomez was reportedly bothered over Bieber's rumored relationship with Kardashian. The 23-year-old reportedly talked to Bieber and confronted him over his rumored relationship with Kardashian, who is 15 years elder to him.
