Rob Kardashian and Blac Chyna

The 27-year-old star is expecting a baby with fiance Rob Kardashian and says the sock designer's older sister - who has children North, two, and Saint, five months, with husband Kanye West - has been very supportive.

Asked if Kim has given her tips, Chyna - who has three-year-old son King Cairo with former boyfriend Tyga - said: "She gives me a lot of tips, actually."

The make-up artist said she feels "amazing and blessed" and has not had any pregnancy cravings so far.

Meanwhile, Rob is very excited at becoming a father for the first time.

In his first on-camera interview in two years, the 28-year-old star told E! News: "I mean it's my first time, so everything is exciting, literally.

"I'm happy and I just like to keep it, you know, keep it private...as private as can be."

The couple's comments come after Kim praised the former model for helping her reclusive brother turn his life around.

Speaking on an upcoming episode of 'Keeping up with the Kardashians', she said: "He hasn't been like this in so long, that even though there's been some drama, if this is what it takes then I don't care who he's dating. I'm so happy that he's just feeling better about himself."

However, her sister Khloe Kardashian - who Rob lived with until his relationship with Chyna was uncovered - didn't seem as impressed.

She shrugged: "If some p***y is getting him to remove his braces and shave his beard and work out...

"Don't we kind of think it's a miracle that Rob, who doesn't even show up to Christmas for the past three years, literally he wouldn't leave his room, but the fact that now he's created a Snapchat ... blows my mind."

Kim replied: "She gave him confidence, more power to her."

However, the 35-year-old beauty was unimpressed with Rob for not showing "loyalty" and letting his family know about his relationship, because Tyga was dating half-sister Kylie Jenner until recently.

She said: "He should have said to us, 'Hey guys, this is how I feel. I can't help who I love. And I fell in love with her. Kylie should know this."
