We're not sure what we just watched...

  • It looks like the upcoming sex comedy “Dirty Grandpa” is pulling out all the stops. And by all the stops we mean Robert De Niro convincing his grandson, Zac Efron to have more fun in his life – because he’s with the totally boring Julianne Hough, ready to marry her. But Robert De Niro’s wife/ Zac Efron’s grandma just died, so Zac decides to take Robert on vacation. So, they go to Dayton Beach – where Aubrey Plaza continually hits on Robert De Niro??

    Yeah, the trailer is as confusing as it sounds – but Facebook was excited enough to get it trending earlier this morning. The movie is slated to release on January 22, 2016 – will you be watching?
