She was partying up a storm on Thursday in Los Angeles for her little sister Kylie Jenner’s 21st birthday.
But Kendall Jenner was sunning herself in Mexican beach resort Puerto Vallarta with friends by Sunday, lounging poolside on a sumptuous deck chair.
The 22-year-old supermodel slid into a turquoise strapless two-piece that allowed her to show off her enviably svelte midriff and shapely legs.
A couple of male pals floated about in a pool in front of her as Kendall lay back on her deck chair and enjoyed the sultry summer sunshine.
This Friday, she swung by the West Hollywood nightclub Delilah, where Kylie was celebrating finally reaching America’s drinking age.
Kendall’s Detroit Piston ex-boyfriend Blake Griffin, whom she split from earlier this year, decided to pop by the party as well.

Wrapped in a gleaming black barely-there mini-dress, Kendall teetered into the fete on stilettos that featured fake flames running up the back.
Potential man drama abounded at Kylie’s bash, as in a slight directed at Tristan Thompson, the allegedly unfaithful beau of Kylie’s half-sister Khloe Kardashian.
Less than 48 hours before Khloe gave birth to his daughter True Thompson this April, DailyMail.com reported on Tristan’s kissing strip club bartender Lani Blair.

Khloe, who during her pregnancy had relocated to Ohio to live with her Cleveland Cavalier boyfriend, moved back to Los Angeles after the baby was born.
Kylie celebrated the shift with balloons welcoming Khloe and True to the City Of Angels, but noticeably excluded the baby’s father from the message.
At Kylie’s birthday party this Thursday, she had a go at Tristan again, leaving him out of a family mural despite his having a baby with her half-sister.

Meanwhile, Scott Disick, the ex-boyfriend of Khloe’s big sister Kourtney Kardashian and the father of Kourtney’s three children, was included on the mural.
So was Robert Kardashian, who along with Kris Jenner sired Kourtney, Kim, Khloe and Rob Kardashian but who was of no blood relation to Kylie.
Khloe was effusive with praise of the mural when she uploaded a photo of it to her own Instagram page, gracefully ignoring the jab at Tristan.
