|Ryan Gosling & Eva Mendes|
The 32-year-old actor previously dated Rachel after they starred together in 'The Notebook' before ending their romance in 2007 followed by a brief reconciliation the next year - and now he's been there for her after her split from Michael Sheen last month.
A source told Now magazine: "Rachel's always kept in touch with Ryan, but now that she's split with Michael, she's been calling him and using him as a shoulder to cry on.
"It hasn't gone down very well with Eva, to say the least, but Ryan wants to be there as a friend for his ex."
Ryan and Eva have been in a relationship since September 2011 and the actress recently admitted it was "adorable" seeing how her real-life partner embraced fatherhood on the set of their new movie 'The Place Beyond The Pines'.
She said: "He's really good. He loves babies and he loved playing with the little boy we used in the film to play our son. It was adorable to see him in that light."
