Oprah Winfrey surprised her best friend Gayle King with an epic birthday celebration that she wasn’t expecting.

Winfrey, 70, posted a video to mark the occasion on Instagram on Saturday, December 14, in which the couple was seen entering a venue before King jumped back in surprise as she was greeted with cheers from her loved ones.

The video then shows a room full of guests singing “Happy Birthday” to a still-shocked King.

“My best friend of 50 years is turning 70, so we gathered everyone who loved her to celebrate,” Winfrey said in the post’s caption. “It’s hard to surprise them, oh the stories we made up, the lies we told to keep this a secret.”

“Happy birthday @gayleking I’m sorry we almost gave you a heart attack,” the star added to King, who turns 70 on December 28.

Earlier this year, Winfrey celebrated the same milestone birthday, albeit with a much more low-key celebration.

The mogul turned 70 on January 29 and spent the big day jogging on the beach. In an Instagram video documenting the moment, Winfrey wrote: “Celebrating her 70th birthday with a run on the beach. #Healthisthebestgift. Thank you for all the birthday love 🥳.”

At the time, King celebrated Winfrey’s special day by posting a sweet video of Winfrey on Instagram. It showed Winfrey spending quality time with King’s grandson during a short vacation.

“I’m happy to say @oprah is still a very good reader at 70!” King said in her caption. “Although favorite grandson Luca is too young to understand how special this moment was during the Christmas holidays, it was not lost on me.”

King then revealed what Winfrey wanted most for her big day.

“When asked how she wanted to spend her birthday, she replied, ‘No presents, no parties, no surprises!’ She loved to sit by the fire with a good book and enjoy the smell of her life! Happy birthday, Oprah!!”
