London - Ellen DeGeneres thinks Ryan Gosling and Eva Mendes will have the "most beautiful" baby ever.

The talk show host has congratulated the couple - who will reportedly welcome their first child into the world in two months time - on the actress' pregnancy and is looking forward to seeing their offspring.

She tweeted: "'Congrats to @RyanGosling and @EvaMendes! That's going to be the most beautiful, bilingual, part-superhero, well-dressed, romantic baby ever. (sic)"

Though the couple haven't confirmed the pregnancy, they are said to be thrilled, particularly 40-year-old Eva who has wanted a child for some time.

A source said: "She's been ready for motherhood for a while now and to be sharing this experience with Ryan is a dream come true for her!"

While the 33-year-old actor - who has been dating his 'Place Beyond the Pines' co-star for three years - is said to be fully committed to the relationship, he doesn't share his girlfriend's desire to settle down and get married.

A source said: "Ryan grew up without a dad, so he always said when he had kids, he'd be there no matter what.

"This is it for him."

Another source added: "Ryan doesn't think they need to marry just because they are having a baby but Eva believes it's important to have their lives fully intertwined." - BANG Showbiz
