Kris Jenner, beau Corey Gamble show some PDA at Haute Living party

Nothing brings the Kardashians out in full force like a promotional appearance.

Fresh off their high-profile St. Bart’s vacation last week, Kim Kardashian, Kourtney Kardashian, Kendall Jenner and Kylie Jenner stepped out on Monday night to celebrate momager Kris Jenner’s cover issue of Haute Living at Nobu in Malibu.

The “Keeping Up With the Kardashians� matriarch, 59, is featured on and in the mag’s August/September issue and talks about Caitlyn Jenner, Kourtney’s split from longtime boyfriend Scott Disick and her obsessions with Chanel and Costco, and takes readers through a day in her life.

“I am living my dream because I get to work with my kids and watch them find their happiness. It’s so rewarding — we brainstorm around a conference table and have a really great time doing it,� she told the mag.

But new love appeared to be on her mind Monday: Jenner, clad in a Christian Siriano dress, arrived at the bash with boyfriend Corey Gamble at 7 p.m. and packed in the PDA with her younger beau, whom she’s been linked to since November. Gamble, 34, is a road manager with Justin Bieber’s manager Scooter Braun and SB Projects.

The couple was later joined by Kylie Jenner, back from 18th-birthday festivities, and her pal Pia Mia. The youngest of the Kardashian-Jenner clan stepped out in a tight brown dress, shed her vacation cornrows and stared into selfies with gray contact lenses.

Kim Kardashian, who is pregnant with her second child, surprised her mom at the dinner and posted about the shindig on Instagram. Incidentally, Mrs. Kanye West just became the most-followed person on the photo-sharing site, edging out singer Beyonce.

Absent from the festivities was Jenner’s other daughter Khloe Kardashian, who instead gave mom a shout-out on Twitter about her cover, writing: “My gorgeous mama on the cover of Haute Living!!!� Jenner’s son, Rob Kardashian, also was absent.

The intimate seaside dinner, replete with photographers and hosted by Westime and Haute Living, included a menu of Shishito, whitefish with dry miso, scallop Tiradito, king crab amazu, black cod miso and beef Tobanyaki.
