Jennifer Aniston wants to look like she ''maybe had a romp'' at her wedding.

The 44-year-old actress recently postponed her nuptials with fiancé Justin Theroux, which were due to take place this summer, because of their increasingly busy work schedules and the ongoing renovation of their Bel Air mansion, but she's still thinking about her hair for the occasion and plans to look sexy, while wearing a traditional veil.

The 'Wanderlust' star told the July issue of Marie Claire: ''For my wedding, I wouldn't do an updo, but I think a veil is always pretty. I like loose and natural hair because it goes against the formality of the dress. Loose, like, 'I just got out of bed, maybe had a romp' hair.''

The actress, who was previously married to Brad Pitt until 2005, admits she is in awe of the Duchess of Cambridge's immaculate hairstyle.

She said: ''Does she do her hair herself? She's got a hard job, being scrutinised like that. When I have a bad hair day, my hair just goes in a clip.''

But she claims her own hair has suffered as a result of over-styling and she now relies on clip-in extensions on the red carpet.

She said: ''I have naturally wavy, frizzy Greek hair, and over the years it's taken a beating from blow-dryers, flatirons, curlers, and extensions, which I think are the most damaging. I couldn't get it to grow because it just kept breaking. Even when it was longer, it didn't look long because the ends were so thin. I ended up using clip-in pieces just to fill it out.

''I'm a creature of habit. I like a good, straight blowout...I love my hair most when we let it go raw and natural.''
