The Super Bowl line-up will include a pair of hotties - Bar Refaeli and Kate Upton have signed up to star in new Tv ads which will debut during the big American football game next month (Feb13).

Leonardo DiCaprio's supermodel ex Refaeli will film a spot for website's annual Super Bowl commercial, alongside regular Danica Patrick, while Upton has been linked to Mercedes-Benz for the car company's new ad campaign.

Both models are former Sports Illustrated Swimsuit Issue cover girls, but it's unlikely either will show off too much flesh in the new ads -'s chief marketing officer Barb Rechterman tells Usa Today, "We're not thinking bikinis or anything like that," while Stephen Cannon, Ceo of Mercedes-Benz Usa, insists Upton will be wearing a cocktail dress for her spot, adding, "We don't have her on the hood of a car in a bikini."
