So, you're Sienna bit more of your ex lover Miss Miller

Sienna has fallen back into the arms of Balthazar Getty - just a month after they split.

Loved-up... and loving it: Sienna and Balthazar wrapped up together aboard their pleasure craft

The pair were spotted on a romantic holiday in southern Italy yesterday, and looked very much like they had put their break-up behind them.

Sienna arrived in Positano with Balthazar's mother on Friday. He didn't appear until yesterday, when they took a boat together to Nerano - where they kissed and canoodled over an intimate lunch.

They joined a group of family and friends for a meal at a restaurant called Lo Scoglio. But Sienna mustn't have been satisfied by her menu choice, as she was spotted trying to eat Balthazar's ear at the table.

The group then made their way back to Positano - the same Italian town where a topless Sienna was first spotted kissing Balthazar on a yacht last year. The 27-year-old was dubbed "Sluttyienna" for hooking up with the married father of four, who is now separated from his wife Rosetta.

Reports emerged last month that the couple had called time on their affair, and Sienna has said in interviews that she is still in love with old flame Jude Law. Make up your mind, love.
