Bruce Jenner was praised as the ''best daddy in the world'' by his children on his 63rd birthday.

The former Olympian enjoyed dinner with his extended family on Sunday (28.10.12) and his daughters Kylie and Kendall Jenner, from his marriage to Kris Jenner, and her children from her marriage to Robert Kardashian, rushed to pay tribute to Bruce.

Kendall wrote on twitter: ''Happy birthday dad! I love you!'' and ''Best daddy in the world.''

Bruce's step-daughter Khloe Kardashian - who recently landed the role of co-host on the US 'X Factor' - also praised Bruce and revealed she and husband Lamar Odom were excited to celebrate with the man who raised her following the death of her own father in 2003.

She tweeted: ''Happy Birthday to the most amazing dad ever, Bruce Jenner. Get ready for dad's birthday dinner! Lamar and I are ready to RAGE! (sic)''

Bruce and Kris have been married since 1991 and while they recently went through a tough patch while filming season seven of their reality TV show, Kris insists they are now back on track.

She previously said: ''Everyone in the family has their own challenges to get through over the course of the season.

''I watch it back and I'm like, 'Oh my God, I can't watch'. It's so crazy painful that I can't watch it.

''Bruce and I are okay and that's all that matters. The kids understand. It's just hard to watch. I just can't wait until season eight!''
