Sylvester Stallone, 73, shows off his natural hair color after abandoning hair dye

Seductive at 73!

Sylvester Stallone has done away with hair dye in recent months, leaving the "Rocky" star looking handsome as ever with white-gray facial hair and a pushed-back coif. Although he's gradually moved on from his signature jet-black locks, he's mostly rocked a darker salt-and-pepper look up until now.

If there was any doubt he's feeling his new look, Sly posted a motivational selfie video on Instagram this week, urging fans to "keep punching."

"Sometimes I wake up I feel like doing nothing. Just relaxing," Stallone captioned the quick video, which he recorded in a car. "If anyone says different, they're lying - it's human nature."

He continued, "Then you roll over, get a little mad at yourself, and realize to get anywhere you've got ot make a deposit in the GOAL BANK. So, I'll go back to my favorite phrase and do it!!"

Perhaps taking his own advice, Sly keeps a busy schedule these days. He's currently filming his next movie, "Samaritan."

He's also a devoted dad, regularly sharing photos of quality time with his kids. In addition to daughters Sistine, Scarlet and Sophia — who, no, are not triplets — he has a 41-year-old son named Seargeoh. Stallone also has a son, Sage, who died in 2012 at age 36.
