The usually contentious couple spent the day sightseeing and shopping in London during the most romantic family vacation we've ever seen!
Scott and Kourtney brought little Mason along to a bridge in London, where they locked up their love for all eternity. During the walk across the bridge, which featured padlocks all along the railings, Kourt and Scott made a vow to each other to 'lock up' their love - literally.
Scott then threw the key in the water and said, "I think it's forever now baby!" as Kourtney went in for a kiss.
One thing is for sure, this is going to make a great episode for Kourt and sister Kim's new reality show! Check out the pictures of this romantic family vacation. Now if only baby Penelope were there ... it would be truly picture perfect!
