On Friday, all eyes were on Amal who looked radiant as she walked through Barcelona airport with her former ER star husband and his parents Nick and Nina, wearing a loose-fitting, camel-coloured jumper dress.

The happy couple recently celebrated their two-year anniversary after marrying in a stunning wedding ceremony in Italy, and George previously opened up about how he proposed to the star. Chatting on the Ellen DeGeneres Show, he said: "I've got it all set up, timed out and the song is coming and she gets up to go wash the dishes, which she's never done. And I'm like what are you doing and she comes back in… I got down on my knee and said, 'I couldn't imagine spending the rest of my life without you.' And she kept looking at the ring and she was looking at me and she was like 'Oh my God'. Finally I literally said, 'Look, I hope the answer's yes, but I need an answer. I'm 52 and I could throw out my hip pretty soon'. And she said, 'Oh, yes' and it worked out really well."
