Simon Cowell, Mezhgan Hussainy completely in love

London (ANI): It looks like Simon Cowell and his fiancie Mezhgan Hussainy just can't get enough of each other. The love-struck couple enjoyed hot caresses and tender smooch just hours after Mezhgan, 37, arrived to London from Los Angeles.

"You couldn't imagine two people more obviously in love. You could really tell they've hated being apart," News of the World quoted a source as saying. "As soon as Mezhgan landed she whizzed straight over to see Simon. She was fussing all over him, stroking his neck, draping her arms around his shoulders then pinning him to the railings for a snog."

"And Simon was running his fingers through her hair, resting a hand on her bum as they moved in close for those lingering kisses. They were carrying on like a couple of teenagers and it was all very sweet," the source added.

Previously there was speculation that the romance was on the rocks because the stars were busy with their work.
