“GIRLS” star Lena Dunham was stunned to discover that her boyfriend Jack Antonoff used to date sultry Scarlett Johansson – and now she’s grilling the tight-lipped rocker about what ELSE he hasn’t told her, say insiders.
Lena – who plays Hannah Horvath on the hit HBO show she created – has dated the guitarist with the pop band fun. for nearly two years. But, incredibly, she had no idea he and Scarlett were high school sweethearts until she stumbled across a picture of them on the website Old Loves.
“My mind is going to explode,” said Lena. “She’s beautiful, he’s beautiful, but it was just so surreal to be looking through this blog…and then there’s my boyfriend.”
