Jude Law supports Sienna Miller

Actor Jude Law bagged a front row seat as he turned out to support his fiancée Sienna Miller at London Fashion Week.

The actress was showing the fourth collection from her label with sister Savannah, Twenty8Twelve on Saturday.

The on-again-off-again couple sent the press into a frenzy as they were seen running around and joking with one another backstage before Jude took up his place in the audience.

The latest collection for Twenty8Twelve, Jericho, was inspired by Joni Mitchell's album Don Juan's Reckless Daughter and the Wim Wenders' film Paris, Texas.

"That's always such a great part of the design process where we all watch movies, listen to loads of music, we go through archives and loads of photography and it's really exciting for us," said Sienna.

The 28-year-old added: "I was traveling in Asia earlier this year and the hill tribes of northern Thailand are really inspirational in terms of colour and print and textile. And yeah, I'm really proud of what we achieved this season."
