Sienna MillerSienna Miller and boyfriend Rhys Ifans reported annoyed fellow passengers on their flight home from Los Angeles earlier this week.

The pair had been in Los Angeles for the award show-filled weekend and for Sienna to start work on her new film GI Joe but returned to London on a flight on Monday evening.

According to reports, the pair began frantically kissing as soon as they boarded the Virgin flight but kept breaking off to whisper to each other then laugh loudly. Then after some play-fighting, the couple stripped off and together climbed into Sienna’s narrow fold-out bed.

A source claims: “They were all over each other and kept disappearing under the little duvet. Then Sienna said she wanted to watch a film but they did more kissing than watching.”

“James McAvoy and his wife Anne-Marie Duff were on the same plane and they just seemed embarrassed by it all.”
