Sylvester Stallone celebrates his 'brave' daughter Sophia 'going for it' and facing her fear of spiders in an Instagram video

• Sylvester Stallone shared a video of his daughter Sophia facing her fear of spiders.
• The "Rocky" star said he's "so proud" of how "brave" she was while letting a tarantula crawl up her arm.

Sylvester Stallone told his 15 million Instagram followers in a video caption that he's "so proud" of his "brave" daughter Sophia, 25, for facing her fear of spiders.

On Monday, Stallone posted a video of Sophia allowing a tarantula to crawl up her arm. "Let's see bravery, let's go Sophia," Stallone, 76, encourages his daughter off-screen right before a handler placed the spider on her body.

While the handler (also off-screen) holds Sophia's hand to steady it, her dad continues motivating her, describing the spider as "cool."

"I'm so proud of you, baby love," Stallone says, as Sophia repeatedly begs the handler to "get him" before the creature can crawl too far up her arm.

"Watch her, she's gonna freak," the "Rocky" star tells the handler as he takes the spider off of Sophia's arm and she runs away from the camera. Sophia's sister Sistine, 24, looks on in shock.

"I'm actually more scared of spiders after doing that...," Sophia wrote in a comment underneath her dad's post.

It's unclear if Sophia has actual clinical arachnophobia, but if she did, she's not alone.

According to the Cleveland Clinic, 3% to 15% of the population has arachnophobia, defined as an "intense fear of spiders" that reaches phobia-level when it "consumes your thoughts, interferes with your daily activities and keeps you from socializing with your family and friends."

Sophia is the oldest of Stallone's three daughters with his ex-wife, model Jennifer Flavin. She was born on August 27, 1996, the year before the couple got married. Sophia has two younger sisters: Scarlet, 20, and Sistine, 24. Sophia currently runs a book club and hosts a podcast with her younger sister Sistine.

Stallone also has a son named Seargeoh, 43, with his first wife, photographer Sasha Czack. Their son Sage died of a heart attack in 2012 at the age of 36, Reuters reported.
