Meanwhile, Kourtney's younger half-sister Kylie Jenner officially kicked off her 20th birthday festivities Wednesday night as she attended Kendrick Lamar's concert for the third time in a week in downtown Los Angeles.

The birthday girl - who turned 20 on Thursday - was joined backstage at Staples Center by her momager Kris, big sister Kendall, and half-sisters Khloé Kardashian and Kim Kardashian West.

The Lip Kit mogul got an affectionate hug from her new rapper flame, Travis Scott, who opened for The Damn Tour's three-night stand in LA alongside D.R.A.M.

Capturing much of the action was 33-year-old Khloé, who will celebrate her first anniversary with Cleveland Cavaliers center Tristan Thompson next month. 

For her special night, Kylie dressed down in a white tank mini-dress beneath a matching hoodie and sneakers selected by stylist Jill Jacobs.

The Keeping Up with the Kardashians stunner - whose BFF Jordyn Woods never left her side - also sported waist-length hair extensions by Tokyo Stylez as she treated herself to a bag of Dippin' Dots. 

Though her sweet choice certainly wasn't reflective of the glamour inside her bash, as Snapchat posts revealed that there was also an ice sculpture of Kylie's hourglass figure, which her included her famous derriere.

Also spotted heading inside the venue was the Jenners' pal Hailey Baldwin rocking Daisy Dukes and thigh-high boots.

Kylie previously spoke about their tight friendship in Sunday's Life of Kylie premiere, announcing: 'I see Kendall, Bella [Hadid], and Hailey - they're out here every day, they just put their outfits together, they're made for this.

'I just feel like this fame thing is going to come to an end sooner than we think. I just don't know who I'm doing it for. Sometimes I wish I can do what they do. But that's not me.'

Earlier on Wednesday, Kylie - who who boasts 138.7M social media followers - shared Instagrams of herself lounging poolside in a nude string bikini while visiting Kris' Hidden Hills mansion.

The sultry snaps only highlighted how much the selfie enthusiast's appearance has dramatically changed since she was a Sierra Canyon School cheerleader back in 2012.

Kylie has admitted to having artificially-plumping lip injections from cosmetic dermatologist Dr. Simon Ourian at his Beverly Hills clinic Epione.
