Rihanna knows when she is having a ''fat day''.

The 'Umbrella' hitmaker has urged women to ''laugh'' at themselves more and not become too obsessed by what the scales read.

She told the June issue of Vogue magazine: ''You've just got to laugh at yourself, honestly. I mean, I know when I'm having a fat day and when I've lost weight. I accept all of the bodies. I'm not built like a Victoria's Secret girl, and I still feel very beautiful and confident in my lingerie.''

Meanwhile, Rihanna's stylist Jahleel Weaver previously revealed he feels ''blessed'' to work for the singer and says he is fortunate to be part of one of the few brands that sees black people as a priority.

He explained: ''I'm blessed to be able to say that and to go to work every day and see black people ... She always says the first woman she saw put on make-up was a black woman - her mother.

''It was natural for her to obviously appeal to that, but also to appeal to all women. Is she the first person ever to offer dark skin foundations? No. But is she the first person to maybe market to them in a very long time?

''I feel like there are some companies now that are seeing there's a demand for this and saying, 'Oh, well we've had this forever.' But it's like, did you not market to them because you thought you wouldn't make money?

''But I'm happy that she started this conversation, to say [to the beauty and fashion industries] 'Hey. These are people and we have a lot of money to spend and if you show up for them, they'll show up for you.'''
