Friends make better lovers, or so the saying goes. Scientists have proven that lovers who always consider each other friends experience better sex and greater committment. It makes sense: connecting with someone on a psychologically, mental, and spiritual level can be essential to a committed, long-term romantic relationship.
These 8 celebrity couples have certainly proven that making the jump from friends to lovers can be possible (and wonderful!)
1. Eva Mendes & Ryan Gosling
Ryan Gosling and Eva Mendes have the picture-perfect romance. The two have been together since 2011, and in September 2014, they welcomed their first child: Esmeralda Amada Gosling. However, contrary to popular belief, these two didn't meet on the set of The Place Beyond The Pines. Sources say they had been friends for years before co-starring in the movie, and didn't start dating until after production had wrapped.
2. Naya Rivera & Ryan Dorsey
Naya Rivera shocked the world when she married Ryan Dorsey in a secret ceremony just months after her split from longtime fiancé Big Sean.

3. Ariana Grande & Big Sean
Speaking of Big Sean, he also made the leap from friend to boyfriend with his current gf, Ariana Grande. The two first collaborated in 2013 for the single "Right There."

Later, after both had split from their respective partners, a romance blossomed. In September 2012, they shocked the world when they announced that they had been married in secret.
5. Jessica Alba & Cash Warren
Jessica Alba revealed that she and hubby Cash Warren developed a friendship before they hooked up, although she always wanted more. "I just knew when I met him that I was going to know him forever," she revealed. "It was weird. He instantly felt like family."

6. Carey Mulligan & Marcus Mumford
In one of the sweetest Hollywood love stories ever, longtime friends and former pen-pals Carey Mulligan and Marcus Mumford married in 2012.

They later reconnected, fell in love, and got married.
7. Mila Kunis & Ashton Kutcher
We all know the story: Mila Kunis and Ashton Kutcher first met in 1998 on the set of That 70s Show, where they played the on-again, off-again couple Jackie Burkhart and Michael Kelso. The on-screen romance didn't continue when the camera turned off. Kunis dated Macaulay Culkin for eight years, finally ending things in 2011. Meanwhile, Kutcher married (and divorced) Demi Moore.
