Kourtney Kardashian's boyfriend and sister still don't speak.

The socialite - who has 13-month-old son Mason with Scott Disick - admits relations between her partner and sibling Khloe Kardashian have got easier in recent months, but they are still strained.

She said: "Now Khloe and Scott can be in the same room. Before they would be like, if Scott knew Khloe was going to be there, he wouldn't come, if Khloe knew Scott was going to be there, she wouldn't come.

"So now they can be in the same room - they're definitely not calling each other like, 'I miss you so much, let's talk,' they don't speak, but they're civil."

In 2009, Scott wasn't even included in a family Christmas card, which Kourtney's mother Kris Jenner selected from a picture taken at Khloe's wedding to Lamar Odom.

Kourtney admitted to US TV talk show host Jimmy Kimmel: "There's progress. Last year, in our Christmas card, Scott was not in it, Ryan Seacrest took his place.

"Scott was like, 'I wasn't even in a wedding picture? No one asked me to even be in one?'"
