(Cover) - EN Showbiz - Jake Gyllenhaal thinks his relationship with Anne Hathaway is rare.

The pair have been praised for their incredible on-screen chemistry in romantic drama Love and Other Drugs, which tells the story of a young couple who embark on a carefree liaison and end up in love.

The pair had previously starred as a couple in 2005 blockbuster Brokeback Mountain, and Jake believes their relationship is very special.

I enjoy thinking about how much I admire her and talking about it because its nice, its rare, he told Cover Media.

In one scene in Love and Other Drugs, Annes character Maggie asks Jakes character Jamie to name the four personality traits hes most proud of. In real life, both stars are reluctant to praise themselves, but happy to discuss each others good points.

I think its testament to how much we genuinely care about each other that we could probably name four good things about each other - and we have because weve been asked that question already a few times, explained Jake.

Anne was quick to point out that they could also highlight negative traits about each other, which Jake agreed with. He believes their bond is so deep that they can be totally honest with each other without any repercussions.

Thats true, he conceded. Sometimes there are flaws and things that frustrate us about each other.

Anne also teased that she wouldnt feel comfortable describing her best attributes. The modest star laughed that she could think of nothing more painful. (C) Cover Media
