Lindsay Lohan has a thing for older men.

The US actress has reportedly got a soft spot for photographer Terry Richardson.

Lohan apparently spent time with the 46-year-old following a photo shoot, and is now keen to start up a relationship with him.

However, according to Radaronline.com, Richardson is 'just not interested,' and regrets spending time with her.

'They had a major night of passion after they worked on this photo shoot together and now she's going all out to get her claws into him,' a source told the website.

'Lindsay and Terry have been friends for years, and she's always had a thing for him. Lindsay thinks he's really cool and hip and could be great for her career.'

The pair's 'steamy night of passion' came after Richardson shot Lohan in a sexy photo shoot at the Chateau Marmont in Los Angeles.

'Lindsay has been texting and phoning him nonstop and he's actually kind of freaked out by how strong she's been coming on to him,' the source added.

It is reported that he is trying to work out a way to let her down gently without blowing their friendship.

One of Lindsay's most recent public appearances was Richardson's pre-Oscar party  - the opening of his latest exhibition, Terrywood.

Just like Lohan, the photographer is no stranger to controversy and has been the subject of sexual harassment allegations on various occasions.
