Bruce Jenner indulged himself with a red manicure just in time for his birthday, adding to the rumors that the Olympian may be transitioning to become a woman.

Bruce Jenner Gives Himself A Red Manicure

Photographers caught Jenner driving around Malibu with freshly painted nails and holding a cigarette on Tuesday. According to reports, witnesses saw Jenner pull over on the Pacific Coast Highway to give himself a quick manicure, all while sitting in the driver’s seat. The witness added that Jenner took out a cigarette, checked his nails and drove off. “It was so strange,” a witness told E! News.

On Wednesday, Jenner celebrated his 65th birthday with a sweet family lunch with his daughters, Kylie Jenner and Kendall Jenner, as well as his three stepdaughters, Kourtney Kardashian, Khloé Kardashian and Kim Kardashian.

Jenner’s odd manicure is the latest in a string of changes Jenner has been making to his appearance in recent years. After getting surgery to flatten his Adam’s apple, speculation emerged that Jenner was questioning his gender identity. The speculation continued as Jenner began growing out his hair, something that was documented on Keeping Up With The Kardashians.

Jenner’s soon-to-be ex-wife, Kris Jenner, recently laughed off rumors that Jenner was transitioning to become a woman, saying, “Just – it’s silly. I mean, they’ve been saying that since the ‘70s. They just keep regurgitating the same old stuff.”
