Sofia Vergara reveals one thing she was self-conscious of while filming sex scenes for Netflix's Griselda

Modern Family star Sofia Vergara might seem like the kind of person who has nothing to be self-conscious about, but even the biggest and most beautiful stars can still find ways to be insecure.

Vergara opened up during a Netflix FYSEE event on Sunday (June 2) about concerns that actually 'kept her awake' at night while she was filming the drama series Griselda.

The 51-year-old actor starred as Colombian cocaine trafficker Griselda Blanco in the series, but among the scenes of drugs and drama, there were also some more saucy moments.

At one point in the show, Griselda shares a passionate moment in bed with her husband, Dario Sepulveda.

While they were meant to be portraying a good time, Vergara admitted she actually had a lot of worries running through her mind.

When asked if she'd ever felt out of her depth during the show, as per The Sun, Vergara responded: "The sex scene. I don’t think I’ve ever done like a sex scene. With Jay [in Modern Family] I didn’t do anything."

"I'm 50! I mean, when I was 30, I wouldn't have worried," Vergara continued. "I think I was worried that I was going to look horrific."

The actor went on to reveal there was one feature in particular that she was concerned about during the shoot, saying: "I was like, 'Where are they shooting me? The cellulite? From the side. Uh, I'm vain I guess. That one kept me awake I think'."

Though Vergara was conscious about what she'd look like while filming, she admitted the scene actually 'came out good' when it was finally released.

"It's really dark and Andy, the director, is very artistic and he made me feel super comfortable and he's like, 'We're never going to stay like a long time on you [the camera]'," she explained.

Vergara's admission comes as she recently told Allure she would be open to having all sorts of cosmetic procedures done if she had the time.

“I feel like you have to take advantage of everything that is out there," she said. "I mean, if you care about aging. Nothing wrong if you don't care about it. It's not the end of the world. But if you do, now there's so much stuff out there.”

The actor said she was going to do 'every plastic surgery' possible when she's 'ready', and admitted she 'would've done stuff already' if it weren't for her job in front of a camera.
