Ariana Grande ''feels sick'' when she sees old pictures of herself.

The 20-year-old singer thinks her fashion sense is gradually getting better and better, so she is embarrassed when she looks back on relatively recent photos and sees what she was wearing.

She said: ''My style has changed so much over time for the better. I look at old pictures even from a few months ago and I get sick to my stomach, it's just so embarrassing.''

And the 'Baby I' hitmaker thinks her current style is ''casual and girly''.

Asked to describe her style in a behind-the-scenes video for Cosmopolitan magazine, she said: ''Feminine. It's pretty casual and girly and classic and chilled, I just wear jeans and peplum tops.''

Ariana recently showed off a flowing new hair style after wearing her brunette locks pinned back in a half-up, half-down ponytail for months, but she has admitted she already hates her new weave.

She tweeted: ''I literally wasn't joking about my weave I got a full out weave just to try it & I want to peel my scalp off and throw it off a mountain top. Pony tail bout to resurrect faster than Jesus... Tryin tho. (sic)''
