Jimmy Carter turned 95 years old Tuesday — becoming the first former US president to reach that milestone.

Carter became the oldest living former president in US history in March when he exceeded the lifespan of former President George H.W. Bush, who died at the age of 94 years, 171 days.

The 39th president, who was born in 1924, left office in 1981 after serving one term in the Oval Office.

Carter has overcome health battles such as a cancer diagnosis in 2015 and a hip replacement in May — and remains engaged in programs through the Carter Center, which he opened in 1982 with his 92-year-old wife, Rosalynn Carter.

The pair live in Plains, Georgia, and will celebrate his latest milestone outside the public eye, they said.
