Rachel was recently interviewed by Drew Barrymore for Vs magazine and talked about her love of dogs - and her obsession with having clean teeth.

'I feel like every time I go to the grocery store I pick up a toothbrush,' she said. 'Also I like to be that friend that when a friend stays over and doesn't expect to that you're like, "I've got a clean, fresh, spanking new toothbrush for ya."'

The star also talked about her love life, saying that she would never date anyone who didn't make an effort to befriend those close to her.

Loved up: McAdams and Sheen are firmly ensconced in a relationship

'[It] may not always work out with everyone but if they don't even attempt to get along with people in my life, I would find that really difficult. I want everyone to be a big happy family.'

It seems that Rachel has found that man, however, with her relationship with Michael Sheen appearing to be stronger than ever.

The pair, who met on the set of Midnight In Paris two years ago have been dating ever since.

They recently worked together on Malick's new film but while Rachel appears in the finished version, her 43-year-old boyfriend appears to have been cut.
