And Sienna Miller showed she was a woman in love as she enjoyed a passionate kiss with Lucas Zwirner during a romantic stroll in Venice on Wednesday.

The new couple were also seen staring into one another’s eyes as they shared a special moment in the street, with Sienna cracking a relaxed smile.
The Alfie star looked casually chic in a red, green and black PVC jacket worn over a powder blue shirt for the trip.
She paired this with baggy cropped jeans and canary yellow shoes.
Her blonde tresses were styled in loose waves while her sparkling peepers were hidden behind oversize shades.

Lucas showed off his hunky frame in a powder blue shirt and khaki green jacket, teamed with navy corduroy trousers, as he held hands with his love.
The couple, who met through mutual friends in New York, went public with their romance last year when they attended her ex Tom’s birthday party in London together.
Lucas, who currently oversees 25 book releases a year as editorial director of David Zwirner Books, is a Yale-educated literature aficionado.
She shares one daughter Marlowe, six, with ex Tom, 33, who is also an actor.
Sienna previously gushed to Harper’s Bazaar that Tom was her ‘best friend in the entire world’ – and that while they don’t share a property, they often stay together to spend mutual time with their little girl.
Admitting their close bond has not broken since they cut romantic ties in the summer of 2015 after four years together, she explained: ‘We still love each other.
‘I think in a break-up somebody has to be a little bit cruel in order for it to be traditional, but it’s not been acrimonious in a way where you would choose to not be around that person.’
The star famously dated fellow A-lister Jude Law on-off from 2003, with the actor famously issuing a public apology to her after having an affair with his children’s nanny.
