Kelis collects hotel slippers.

The 'Milkshake' hitmaker has admitted that she likes to keep her feet warm by wearing slippers around the house and confessed she collects the free pairs that are provided in the many hotel rooms she inhabits while on tour.

Quizzed on whether she wears them, she said: ''Always. I kind of have a thing for hotel slippers. I collect them. I have tons and tons and tons of hotel slippers.''

The 34-year-old star claimed that although she is currently living in hotel rooms while performing across the world to promote her new album 'Food', she doesn't like to live out of her suitcase and instead chooses to unpack every time she moves.

She said: ''When I'm touring I have a habit of taking everything out of my luggage all the time and spreading it everywhere.''

Kelis - who split from her husband Nas, with whom she has five-year-old son Knight, in 2009 - also admitted that she's not as interested in the celebrity lifestyle as she was when she was younger.

She added in an interview with Stylist magazine: ''I'm not as adventurous as I used to be. I just don't care anymore. I don't have the same excitement about stuff as I used to.
