Supermodel Miranda Kerr would love to cut her hair short and says she had a strong urge to do so when she was pregnant with son Flynn.

The 31-year-old, who has three-year-old son Flynn with estranged spouse Orlando Bloom, would love to chop off her lengthy locks, but hasn't been brave enough to give herself a drastic makeover yet.

"I wanted to cut my hair when I was pregnant. I had such an urge to cut it really short,` contactmusic.com quoted Kerr as saying.

"I'd like to and you'll see I'm sure in a few years. I have a (faux bob) though. I like to mix it up. One day, I'll cut it for real,` she added.

The former Victoria's Secret Angel takes good care of her hair and can't bear to leave the house without clean tresses.

`I can't leave home without having fresh, clean hair. I wash it every second day unless I'm working back to back days, then I like to keep it fresh. There's nothing better for me after I've freshly washed my hair and I'll let it dry on its own,` she said.

`I just love that feeling of clean hair because it's like a little luxury in life. After I get off an airplane, the first thing I do is wash my hair. If my hair is not clean I don't feel my best,` she added.
