Like Justin Timberlake and Jessica Biel, Amanda Seyfried and Ryan Phillippe split up and got back together again. Unlike Justin Timberlake and Jessica Biel, they then promptly split again. The actor might not be ready for dating after becoming a dad again this year, but we wouldn\'t mind seeing Amanda get back together with other ex Dominic Cooper next.
