Ryan Gosling and Eva Mendes 'welcome second baby'

They certainly kept that quiet!

Eva Mendes and Ryan Gosling have reportedly welcomed their second child into the world!

They're known as one of Hollywood's most stunning couples, and are incredibly private about their personal life. In fact, it was only two weeks ago the news broke that the pair were expecting their second child together. But according to reports from TMZ, the actor duo, who've been together since 2011, have already welcomed a baby girl.

Eva, 42, and Ryan, 35, already have a 19-month-old daughter - Esmeralda Amada - together. According to a birth certificate obtained by TMZ, the couple welcomed their second little one just after eight in the morning on 29th April at Providence St. John's Health Centre in Santa Monica, California. And they've gone for a very special name for their newborn!

The couple have apparently named their daughter Amada Lee Gosling. Amada, a name they've also given to their first daughter, is the name of Eva's grandmother and was also the name of a character she played in 2007's We Own the Night. It means 'beloved' in Spanish.

Eva and Ryan, who've been dating since September 2011 after meeting on the set of their film The Place Beyond The Pines, also kept their first pregnancy under wraps, keeping it a secret for months and then making sure Esmeralda wasn't in the public eye for most of her first year.

Although notoriously private about his family life, dad-of-two Ryan said in a recent interview with the Canadian edition of Hello! magazine that his family is his 'biggest investment'.

'I'm with the person I'm supposed to be with - I'm not looking for anything else beyond Eva - and I feel very lucky that we have a beautiful, healthy daughter, who is an angel. That's investment enough for me.'

When asked how he finds being a father, Ryan added: 'You'd have to ask my girlfriend really - all I can say is that it's important for me to be there for my daughter and that I want to be there too, because it's so fun. Being a dad isn't rocket science - I can handle it.'

Congratulations to the new family of four!
