Khloe Kardashian is thrilled with her family's Christmas card and can't believe how cute her nephew looks in the family portrait.

The 26-year-old socialite has joined her famous sisters and the rest of her relatives for their annual festive photo and insists 12-month-old Mason - her sibling Kourtney's son with her boyfriend Scott Disick - looks like a "little gentleman" in his suit.

Khloe wrote on her blog: "Christmas cards have always been a REALLY big deal in my family. For as long as I can remember, my mom has made it a point to go all out, whether it was a ninja turtles themed card, or bringing a Santa into the mix, each year she always managed to top the year before. I'd have to say though that our card this year might be my favourite. It turned out beautifully - just SO glam!

"Plus, Mason is in it, which makes it even more special. Look at him standing there in his pinstripe suit, such a little gentleman!!! LOL. I love it! (sic)"

The Kardashian family have a tradition of posing together for a Christmas portrait every year and unveiled their 2010 card on Thursday (16.12.10).

All 11 members of the extended Kardashian family feature in the photograph, including matriarch Kris, her husband Bruce Jenner, Kim, Khloe and Scott, Mason, and Kourtney and her husband Lamar Odom.

Kim, 30, wrote on her blog: "We have a lot of traditions in our family, but I think our family Christmas card tradition is one of my favourites."
