Rihanna buys nice lingerie when she's single to give her ''hope'' she'll find love again.

The 'This Is What You Came For' hitmaker - who is currently in a relationship with Hasaan Jameel - has confessed she is a bit of a ''collector'' of lingerie and buys a lot of items in the hope she'll wear it ''one day''.

She said: ''I'm a lingerie collector and half of it I've never worn. I just bought it because I love it, and I feel like if I ever wear it, it'll be for me. Half of it I bought when I was single is what I'm trying to say. It gives you hope in a way, doesn't? One day I'll wear this.''

And the 30-year-old singer - who has just released her own lingerie collection, Savage x Fenty - thinks nice lingerie should make you feel sexy, confident and comfortable.

She added to E! News: ''You definitely want to feel sexy. You want to feel confident. You want to feel comfortable. It's hard to put all those things into one, but those are the things women look for when they are going to buy undergarments or lingerie.

Meanwhile, Rihanna previously admitted she knows when she is having a ''fat day''.

She shared: ''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.''
