Khlo Kardashian thinks most Hollywood romances "collapse" because of the constant scrutiny.

The reality TV star is married to basketball star Lamar Odom, 32 and the pair have their own reality TV show. Although Khlo sees the perks of her series, the star also admits that being in the spotlight does take its toll on relationships.

"It's really difficult having a relationship in the limelight because people are constantly analysing your every move," she told British magazine Closer.

"When I go out partying with my sisters without Lamar, everyone starts saying there are problems with our relationship. I think that's one of the main reasons so many Hollywood romances collapse. It's hard being under so much pressure all the time."

Khlo adores her beau. The stunning star has confidence that their marriage will last.

"I really fancy my husband because he's so hot, but the most important thing is we're best friends," she gushed. "We both travel a lot, so time just hanging out at home watching movies in beds is precious."

Khlo is famed for her cheeky antics on the show. However, the star still cringes when watching back certain scenes.

"We were in fits of giggles when we saw the episode where we jokingly tried out a sex swing and it broke. I cringed with embarrassment!" she laughed.
