Mary J. Blige and Jennifer Hudson Power Walk with Oprah

Mary J. Blige and Jennifer Hudson joined Oprah Winfrey in New York City on Mother’s Day to cut the ribbon to signal the start of the Live Your Best Life Walk. The Oscar-winning mother sang “Happy Birthday” to the media queen in honor of O, the Oprah Magazine‘s 10th anniversary.

“Spending my first Mother’s Day at the Live Your Best Life Walk is a really fun experience to encourage others to get moving and help support the benefiting charities,” said Hudson, whose new album is due in September.
