Eli Roth loves his girlfriend Peaches Geldof because she is "great in bed".

The 'Last Exorcism' director is madly in love with the socialite and says she drives him wild between the sheets.

And Eli, 38, is angry Peaches, 21, gets labelled with the reputation as a party girl because the person he knows is intelligent and socially responsible.

He told German magazine Gala: "Peaches is sweet, sexy, funny and one of the most amazing people I have ever met. I love every inch of her.

"You know what? It annoys the heck out of me that the media keep trashing her and try to label her as a club slut.

"When she was a teenager, she would write socially critical columns for the Daily Telegraph newspaper. Peaches is extremely grown-up, considering her age - and of course she is great in bed."

Eli has also quashed speculation the couple are engaged insisting The Ring Peaches has been seen wearing is just a present from one of her pals.

Referring to the ring, he said: "That is just a gift made by a gay friend."

Eli and Peaches have been dating since March and shortly after they started dating the British beauty moved to Los Angeles so she could be near the filmmaker.
