Lily Aldridge will wear her mother's old Playboy costume for Halloween.

The 28-year-old model - who is married to Kings of Leon singer Caleb Followill - found her mum Laura Lyons' raunchy Playboy Bunny flight attendant costume recently and is looking forward to donning it for the first time during the spooky celebration this evening (31.10.14).

She said: ''I'm wearing it for Halloween, it's so amazing, so 70s, so cool.''

Lily was a teenager when she discovered a copy of Playboy in her father Alan Aldridge's art studio and when she went to tell her mother, 60, she was even more shocked to learn her parent was one of the famous Playmates featured in the adult publication.

However, the Victoria's Secret beauty thought it was ''cool'' and couldn't wait to tell her friends.

She added to GQ magazine: ''I actually started freaking out, so I ran upstairs to tell my mom he was reading Playboy. She didn't break the news at first, just said, 'Well, actually, I'm in Playboy' but said it was because she was at a party.

''Then after a few hours of interrogation, I got her to tell me the truth. But I thought it was the coolest! I went to school and told all my friends.''
