If Amanda Seyfried was looking for a strong man, she seems to have found him.
The Mamma Mia! actress was spotted on a shopping trip with her new boyfriend Ryan Phillippe, who put his muscle-bound arms on show in a white vest.
While the Cruel Intentions star looked every inch the Hollywood heartthrob, Amanda looked a little dishevelled in a grey T-shirt, shorts and unbrushed hair.
