Bar Refaeli will model her own innerwear line when it launches in January.

The Israeli-born supermodel has created a range of items to be worn close to the skin including undershirts, tights and camisoles for her new brand Undeez and Bar insisted all items from the comfortable basics line were personally approved by her.

She said: "We have professional designers, of course, but my ideas and input go into every single item. I try everything before it's manufactured. I choose the fabric and have the last word on the items."

The collection, which is targeting the affordable to midrange price segment, is aimed at people age 25 to 45.

Before posing for the brand in January, Bar will most likely increase her workouts as she has previously revealed she makes sure to do extra exercise if she's got a big shoot coming up.

She said: "I always want to look my best on a shoot, or for a fashion show, so I do an extra couple of sit-ups the night before and I drink hot water with lemon to get my metabolism kick-started in the morning and to cleanse my system, but I don't do anything crazy.

"There's nothing worse than forcing yourself to spend hours in the gym when you don't enjoy it, so I do all sorts of things to work out because I get bored easily."
