Orlando Bloom was reportedly ''flirting'' with Nina Dobrev over the weekend.

The 'Lord of the Rings' actor - who split from wife Miranda Kerr, the mother of his three-year-old son Flynn, last October - attended a number of Comic-Con parties in San Diego with the 'Vampire Diaries' actress and the pair appeared very close.

Orlando arrived alone at Playboy's 'Bates Motel' party on Friday (25.07.14) night, but was soon joined at his table by Nina - who recently split from her co-star Ian Somerhalder - and the pair were seen ''talking closely'' while he drank tequila.

The pair then left together and were spotted after midnight at the exclusive Nerd HQ party, where they were ''dancing very closely, flirting, laughing and whispering in each other's ears''.

The source added to the New York Daily News newspaper's Confidenti@l column: ''Orlando is usually reserved, but he had his hands around her waist and he was dancing with her very closely. At one point, I really thought they were going to kiss.''

While Orlando, 37, appears to be growing close to 25-year-old Nina, it was recently claimed his ex-wife is still romancing James Packer and was spotted making secret visits to his New York hotel, despite previously denying she was dating the Australian billionaire.
