Rihanna thinks North West is ''the bomb''.

The 'Rude Boy' singer gushed over the 17-month old tot - who is the daughter of Kim Kardashian West and Kanye West - when she bumped into Kim, 34, at the Diamond Ball in Beverly Hills on Thursday (11.12,14), and told the reality TV star her child is ''one of the most gorgeous babies, ever.''

According to HollywoodLife.com, she said: ''North is one of the most gorgeous babies ever. [I] could pinch her cheeks all day.''

The 26-year-old singer also raved about the youngster's ''bad baby'' style and asked Kim to help her shop for clothes for her own baby in the future.

According to a source, she said: ''And the way you dress her, Kim, she's one bad baby! When it's my turn, you're coming shopping for clothes with me because your girl is the bomb.''

The brunette beauty was thrilled with the compliments and replied: ''Aww, thank you Rihanna. That's so sweet of you to say.''

Kim is also said to have showed the 'We Found Love' hitmaker a number of adorable photographs of North, which prompted her to say: ''Does this baby take any bad pictures?''

Kim simply replied: ''Nope!''

Rihanna isn't the first person to admire the youngster's fashion choices.

Earlier this year, North was photographed for former Vogue Paris editor Carine Roitfeld's CR Fashion Book in a spread devoted to the 'Legends' of the fashion world.

The toddler was shot for the feature by famed photographer Michael Avedon sporting a Chanel cashmere sweater and miniature studded handbag, along with the brand's signature pearl earrings.
