Ashton Kutcher huddles Valentine's Day co-star Jessica Alba into his coat the the film's London premiere tonight but leaves wife Demi Moore to brave the sub-zero temperatures Any Hollywood star worth their salt never lets a little thing like the elements get in the way when there's a premiere to attend.
Take Demi Moore for example, who braved a freezing London tonight to show off her barely-there dress on the red carpet.
Thankfully husband Ashton Kutcher was on hand to gallantly shared his coat with his leading lady - but he left his wife to shiver in the sub-zero temperatures.
The 32-year-old actor came to the rescue of Jessica Alba, 28, at the London premiere of their new film Valentine's Day at the Odeon Leicester Square as he snuggled her into the right side of his coat.
And although Moore, 47, was probably not best pleased to see her husband favouring another woman's wellbeing over her own, she was all smiles as she showed off her stunning black dress decorated with big white flowers.
Kutcher eventually joined his wife outside the cinema for the celebrity screening of the romantic comedy, but still didn't offer to protect her from the cold.

After arriving in the capital with Moore last night, he wrote: 'London is on good form. Big premiere tomorrow night'.
This morning, in reference to the British dialect, he added: 'Another day of press for Valentine's day. Only this time with a posh accent mate.
Valentine's Day, which follows the intertwining stories of couples on the most romantic day of the year, is released across the UK tomorrow and stars Kutcher and Alba alongside Bradley Cooper, Jessica Biel, Jamie Foxx, New Moon star Taylor Lautner, Anne Hathaway, Patrick Dempsey and Julia Roberts and her niece Emma.

And while Alba was also dressed for warmer climes in a short sleevless green and black checked dress, she at least had the foresight to protect her long legs from the cold in thick black tights.
