The 32-year-old appeared in a brief video recording on her mother Kris Jenner's daytime chat show.
In the pre-taped segment, she surprised the matriarch with a short message, saying: 'Hi Mom, I just wanted to say congratulations on your new show. I am sorry I could not be there, but I am loving life at home right now.
She's back! Kim Kardashian made a brief appearance in a video message on Kris Jenner's chat show on Friday'You are really are born to do this… I Just want to say I love you and congratulations on the show.'
She looked happy and healthy in the clip dressed in a white top.
It wasn't quite the big reveal many fans had been hoping for and there was no sign of her daughter North West.
Kim, who welcomed her first child with Kanye West on June 15, was last seen in public in an olive green dress on June 12.

On June 29, her sister Khloe posted a head shot of her sleeping on the couch at home.
Kim's absence from the spotlight has been rather unusual for the reality star, who has relentlessly pursued media attention from the moment her sex tape was 'leaked' in 2007.
There have been suggestions Kim has been laying low while she gets back into shape. Her boyfriend Kanye, who doesn't share her affection for publicity, has also encouraged her to be more private.
Her best friend Jonathan Cheban recently said she has almost regained her pre-pregnancy body.
He said: 'Knowing Kim, I'm sure she looks 80 per cent at this point, she's pretty much perfect.'
Kim's video will no doubt be a welcomed boost for Jenner, who has struggled to win over critics with her daytime show.
