Sylvester Stallone's 18-year-old daughter, Sistine, flashes her bra at Dior event

Sylvester Stallone may want to look away.

The "Rocky" star's daughter, Sistine Stallone, 18, flashed her fans when she stepped out on Wednesday to attend the launch of Dior Addict Lacquer Stick at Delilah's in Los Angeles.

Sistine stole the show in a black floral, lace top that was completely sheer and showed off a black bra underneath. She teamed the risque look with a black miniskirt and a blazer and a set of platform heels. She added a pop of color with a red clutch and a deep smoky eye.

Sistine is no stranger to pushing the boundaries. Stallone's stunning kiddo knocked it out of the park earlier this year when she hit the stage as Miss Golden Globe alongside her sisters in a knockout dress. In 2016, she was also named an "It girl" by Town and Country Magazine. And lately, she's also been hitting the runways as a high fashion model. She most recently walked in the Dolce & Gabbana show during Milan Men's Fashion Week in January.

Look out world -- Sistine Stallone is making a name for herself.
