Paris Hilton is "so happy" for Kim Kardashian's success.

The blonde socialite first met the Keeping Up With the Kardashians star - who is pregnant with boyfriend Kanye West's baby - in school, long before Kim's career took off and despite feuding over the years, Paris is happy for her pal's achievements and wishes her the best in life.

"I'm so happy for [Kim]. I'm happy for all my friends. I always wish everyone the best. It's important in life, it's important for good karma and I'm so happy to help anyone out. She's always wanted a little princess, I can't wait to see how she dresses her up. It's going to be a beautiful baby," Paris said.

Paris, 32, is also over the moon with her own love life praising her boyfriend River Viiperi, 21, for having "such a big heart." She added, "He's so sweet. He has such a big heart. I trust him so much. I'm really happy."
