Together – again.
Only days after she was photographed kissing estranged husband Bruce Jenner
on the cheek after a holiday weekend movie with her mom in Calabasas, Calif., Kris Jenner posted an Instagram photo
of herself getting silly with close pal Ben Flajnik during dinner at Nobu in Los Angeles on Tuesday.
Posing with pouting duck lips, Jenner, 58, was joined in the group photo by her girlfriend, entrepreneur Liz Heinlein. She captioned her shot of the threesome: "Date night with Ben and Liz."
But what's a night out without a little entertainment? After their meal, the trio caught up with Jenner's daughters Khloé Kardashian Odom
and Kendall for Beyoncé
's concert at the Staples center – the singer's latest stop for her Mrs. Carter Show World Tour.
alum Flajnik, 31, denied last month
that he and Jenner were having a fling after dating rumors arose when he was photographed driving her Bentley. He later said was it borrowed while she was of town. He was also seen on vacation with her in Mexico and at his winery
in Sonoma, where they were joined by Kardashian family pal Jonathan Cheban.
"She's a beautiful, smart woman," Flajnik told PEOPLE of a rumored relationship, noting he was upset by all of the gossip.
"Kris is a very, very dear friend of mine," he said. "We are not dating, we're just working on a couple of projects together, so that's why we've been seen a lot as of late."
