Mary-Kate Olsen 'learned' how to brushed her hair last week.

The screen beauty - who recently got engaged to her partner of two years, Olivier Sarkozy - has poked fun at her own skills in the beauty department.

Speaking to US Elle magazine, she said: ''You know, the truth is I feel like I just learned how to brush my hair like last week!''

Her twin, Ashley, on the other hand seems to be more talented in the beauty department.

She confessed she'd chopped her pal's long hair but had to call a professional to add the final touches to the look.

She explained: ''My friend actually also made me cut her hair the other day and that didn't look too bad either.

''She had long hair, too. It was down to here [salutes to her belly button] and I cut it up to here [points to just below her shoulder]. She made me do it, but it looks great. I made it a blunt, A-line haircut. And then we had a professional come in after and clean it up a bit! But it was pretty good on its own.''
