Kendall Jenner: 'We're so happy to hang out with Rob again'

Kendall Jenner is overjoyed that her brother Rob Kardashian is back in the family fold.

The reality star and fashion model shared her excitement about celebrating her half-brother's 29th birthday at a beauty launch for Estee Lauder on Tuesday night (22Mar16).

"It's all really amazing and we're just very happy to kind of see him and kind of hang out with us again," Kendall shared with E! News' at the Estee Edit by Estee Lauder launch event held at New York City's Sephora. Fans turned out to see the star unveil the line which included a custom eye shadow palette she designed for the brand even though she's admitted she doesn't really love wearing a lot of make-up.

Kendall, 20, and the Kardashian family were all present to celebrate Rob last weekend (19Mar-20Mar) at a birthday party at Nobu in Malibu, two days after his birthday.

Meanwhile, Rob's return to the family fold has also been welcomed by his mother. The once-reclusive sock designer resurfaced soon after he began dating video model Blac Chyna, who is the mother of rapper Tyga's son King Cairo. Tyga is dating Rob's younger half-sister Kylie Jenner.

Speaking on Australia's The Kyle and Jackie O radio show Kris said: "He feels so much better about himself since they started dating. He is doing really, really well. He is trying to be healthy and get in shape and he is also working on a couple of projects."

However, the 60-year-old admitted she hasn't yet got to know Rob's 27-year-old girlfriend.

"I don't know too much about their relationship.... She seems like a really nice girl but I just haven't been around her," she admitted.
