Ryan Seacrest: Rob and Chyna will be ‘exciting’

Ryan Seacrest thinks Rob Kardashian and Blac Chyna’s reality show will be "exciting".

The couple – who got engaged in April after a whirlwind romance and are expecting their first child together – have signed a deal with E! for six 60-minute episodes of ‘Rob & Chyna’ and the program’s producer has promised fans to expect the unexpected.

He said: "You can never guess what to expect with that family, but I think it’s exciting for them–this time for them. I think because they’re expecting.

"I think they’re excited to have this opportunity to show the world what’s going on with them.

"There’s so much paparazzi coverage. There’s so much talk about them that I think they’re excited to show the world what’s happening with them."

Rob has been working hard to lose weight after retreating from the spotlight when he piled on the pounds and Ryan is very impressed by his recent transformation.

He told E! News: "I used to run with him on the treadmill.

"He stopped for a little bit, but he’s looking so much better."

Chyna – who also has three-year-old son King Cairo with ex-boyfriend Tyga – recently revealed her pregnancy is leaving her very tired, though she is thankful not to have been suffering from morning sickness.

She said: "If you guys were wondering, I’m actually having a really good pregnancy, similar to King’s. No morning sickness, no cravings, just baby.

"I swear I wish I had the energy to wake up and do my makeup every day.

"I would post so many more videos and pictures, but I just don’t have the energy."

The make-up artist recently admitted she wants to gain "100lbs" during her pregnancy.

She said: "My goal is to gain, like, 100 pounds this pregnancy. Imma tear it up, then Imma snap back."

And so far, she has gained over 26lbs, as she revealed her pre-pregnancy weight was 139lbs.
