Martha Stewart is in her 80s but is not ready to lose her youthfulness and vibrancy.

The Celebrity chef revealed that she has an agreement with friends that helps her stay young.

She explained that the agreement was to prevent her from "acting like a little old lady.”

According to Stewart, if they ever start acting like old ladies, they will “get killed.”

Stewart also revealed that she enjoys horse riding and Pilates is her best form of exercise.

She noted that she maintains her youthfulness by eating healthily, spending time with loved ones, and visiting the gym regularly.

The media mogul opened up about how much she loves spending time with her grandchildren.

Stewart took her grandchildren to Madagascar and bonded over a visit to a preserved jungle.

According to the iconic chef, a healthy lifestyle for her is non-negotiable.
