Keeping Up With The Kardashians star Bruce Jenner debuted his new hair style on Saturday, when he attended an Elton John concert at the Staples Center in Los Angeles. The 64-year-old former Olympic athlete finally let down his long, brown locks after months of wearing it in a ponytail. Jenner has reportedly been growing his hair since his split from wife Kris Jenner.

On Saturday, Jenner let loose his shoulder-length hair, which reportedly looked healthier and more lustrous than his previous hairstyles. New York Daily News reported that Jenner had been sporting a ginger mullet only a few weeks back. His current hairstyle apparently looks like a throwback to the way he wore his hair in the 1976 Summer Olympics, where he bagged the gold for the decathlon in Montreal.

Jenner was seen with his son Brandon Jenner and daughter-in-law Leah, who were there to watch the concert with him. Jenner was reportedly in the company of a mystery brunette, making the outing seem more like a double date. Daily Mail reported that the brunette bore “more than a passing resemblance” to Jenner’s wife Kris, down to her all-black ensemble of skinny leather pants and shirt.

Jenner himself reportedly looked as if he had styled his hair, since it fell around his face in soft layers instead of being the coppery frizz he used to wear trimmed above his ears while married to Kris. Jenner wore a checkered shirt on top of blue jeans instead of his usual ensemble of polo-shirt and shorts, making an effort to look great that night.

Just the day before, Jenner wore a casual ensemble of gray athletic pants, striped polo-shirt and a pair of army print slip-on shoes while running errands in Los Angeles.

Jenner recently filed for divorce from wife Kris almost a year after they split.
