Why Is Ryan Gosling's Mom Wearing Eva Mendes' Clothes?

We've heard of girls wearing their boyfriend's clothes, but we've never heard of moms wearing their son's girlfriend's clothes... until now! Uber-hunk Ryan Gosling attended the premiere of his highly-anticipated movie Gangster Squad in Hollywood on January 7th looking as stylish as ever. Girlfriend Eva Mendes wasn't able to be by her bfs side, so Ry-Gos treated his mother Donna Gosling to a night of Hollywood glitz and glamour! Donna showed off her sweet style in a ruched dress, a paisley trenchcoat and a statement necklace. However, the press soon found out she had gotten her impeccable red carpet look from Eva herself!

"My mother's wearing all my girlfriend's clothes," Ryan confirmed to E! News.

"I'm wearing Eva Mendes," Donna admitted. "She let me raid her closet."

Wow! It must be something very serious if Mama Gosling is wearing Ryan's gal-pal's wardrobe. 

Would you ever let your boyfriend/girlfriend's parent borrow your clothes?
