Khloé Kardashian is ''unbelievably happy'' with Tristan Thompson.

The 32-year-old reality TV star is so smitten with the basketball star - who will turn 26 on March 13 - that she is even skipping her best friend Malika Haqq's upcoming birthday celebrations to spend time with him on his special day.

Malika - who will be 34 on March 10 - told Us Weekly: ''She is so unbelievably happy and I couldn't be happier for her. [She's doing] amazing.

''My real goal is to celebrate my birthday every year somewhere where I haven't been, so it starts this year. It's a complete girls' trip to the Dominican Republic. Khloé is not going to make it. Her boyfriend's birthday is actually March 13, so she will be with him, but we are going to connect and celebrate together.''

Meanwhile, Malika recently split from 'Jersey Shore' star Ronnie Magro after just a few weeks of dating but insists she is happy to be single.

She said: ''I'm very single. We don't speak [anymore]. I wouldn't say it's on bad terms, but it's not all that comfortable.''

Malika previously enjoyed a brief flirtation with Khloe's younger brother Rob - who is now in an on/off relationship with Blac Chyna, the mother of his four-month-old daughter Dream, but admitted she rarely sees him these days.

She said: ''I haven't seen Rob in a very long time, but I look forward to seeing him. We need to set it up so I can see him and the baby too. ... I hear he's on a great path. I hear good things.''
