Allison Williams definitely has her father's support.

The "Girls" star's famous dad, NBC Nightly News broadcaster Brian Williams, told New York Magazine that he isn't phased by his daughter's racy and uncomfortable sex scene on the HBO. 

Fans that tuned in to the season four premiere of the HBO series were probably left a bit shock after being shown an explicit sex scene involving Williams' character, Marnie, and her partner Ebon Moss-Bacharach, who plays Desi.

"She's always been an actress," the newscaster recently told Vulture. "For us, watching her is the family occupation and everybody has to remember it's acting, no animals were harmed during the filming, and ideally nobody gets hurt."

Allison said her parents are not "veterans of the show, so their thinking has changed as well."

So how did the 26-year-old "Peter Pan Live!" star deal with filming the awkward sex scene?

"I read it in the script and I went into total action mode," she said. "I got everyone together and I was like, 'All right, Grace [in wardrobe], you and me - we're going to come up with something so ingenious that he is going to feel comfortable.'"

She added, "I grabbed the makeup girl and said, 'I want to smell like a cake,' so we put vanilla cream everywhere so everything smells good. And then I'm like, 'Grace, we're going to rig something invisible from the side but that feels like a pillow when he puts his face into it.' It's total TV magic."

Unfortunately, the same cannot be said for Allison's co-star Jemima Kirke. The actress confessed that the idea of watching a sex scene with Williams' father left her mortified.

"I sat behind Allison and her dad," she told the mag, "and I was going to puke. I was so nervous. I don't even know him, but can you imagine? Watching a kissing scene with my dad next to me is awful, let alone with you getting - whatever that's called - motorboated in your ass!"
