Amber Rose doesn't ''want to have sex''.

The 31-year-old model recently revealed she is dating 25-year-old rapper Machine Gun Kelly, but confessed she has no desire to make love to the musician because she is too busy with her two-year-old son Sebastian, who she had with her estranged husband, 'See You Again' hitmaker Wiz Khalifa.

She told Cosmopolitan magazine: ''I don't even want to have sex.

''I really don't! I'm just so focused on my son and my work and everything that I'm trying to do. I just don't even wanna be bothered.''

The news comes just weeks after she announced her relationship with the musician, who she praised for being ''a really nice guy''.

She said: ''We're dating. We're just getting to know each other.

''He's a really nice guy. He treats me really, really nice, and I have a blast with him''

The news of her new beau came as a shock, as the former stripper - who is gearing up to release her self-help book 'How to Be a Bad B***h' - admitted in April she still hoped to get back together with Wiz, after separating from him last September following 14 months of marriage.

She wrote on Instagram: ''We went wrong somewhere and even if we never ever get back together ( Even tho I pray, dream and hope we do) he will forever be the love of my life. The media doesn't make it easy but f**k them we gotta live for reality and not society. We forever have a bond because we made a beautiful baby from our Love. Through all the ups and downs of our relationship my heart still beats for him every single day. (sic)''
