Ryan Gosling is not ready to move in with Eva Mendes according to reports.

The 'Gangster Squad' actor apparently refused to cohabit with his actress girlfriend who it emerged he was dating last September.

An insider claims 31-year-old Ryan wants to take their relationship at a slower pace than the 38-year-old 'Girl In Progress' star would like.

The source told Us Weekly: "He says he wants to slow down and not live with her yet. But he doesn't want to lose her."

'The Place Beyond the Pinescostars' costars were rumoured to be experiencing problems in their romantic partnership in April.

But the pair squashed the speculation with a hand-holding coffee run near Ryan's East Village New York City property earlier this month (10.05.12).

Meanwhile Eva has revealed that her mother is her toughest fashion critic.

She said: "Normally I do something on the red carpet and wherever I am in the world she sends me a full email within minutes with everything she thought of my outfit.

"It's really super cute. It's not like crazy. It is never negative, it is always constructive. It's like, 'Eva, I don't know about that lipstick but that dress was gorgeous!' And then it will say, 'Hmm, your shoes? But your hair was lovely!"
