We all know that awkward moment when you're watching a film with your family and no matter how old you are, as soon as the two main stars start getting hot and heavy there's an immense sense of embarrassment that floods through the room.
We can't explain it Heatworld Citizens, we like to think of ourselves as mature but we remember the cringe-worthy struggle as we tried to come to terms with the fact that our mum wanted to watch Sex And The City with us.
So, we can understand Zac Efron feeling the exact same way, although we suppose it's ten times worse when your mum's watching you go about your business on the big screen.
The actor claims that he tried to 'duck out' of the screening for his new movie The Lucky One because he was horrified that his mum was about to see to see those inevitable sex scenes. Zac says,
"We saw the film together and I was kind of squirming...Even though she was a couple of seats down from me, I tried to duck out during those scenes because it was too embarrassing. Obviously I'm acting, but knowing that my mom and my family were watching is kind of awkward. There's really no way around it."
When we learnt a little more about the details of some of these scenes we almost wanted to cringe with Zac, as one of them shows his character Logan enjoying a shower a little too much. The star continued,
"She was just laughing about it in a good way...She said, 'That's my boy!' I think she was proud of me at the end of it, even if it was weird for her to watch. My mom is my biggest supporter."
It's nice to know that the actor's mum is so supportive. Still, if we were in his shoes...we probably would've ducked out!
