Sarah Ferguson shares her ex-husband's Pitch@Palace event on Instagram.

On Wednesday, the Duchess of York took to Instagram to show her support for Prince Andrew's Pitch@Palace initiative that aims to help entrepreneurs accelerate their business ideas by connecting them to potential investors, mentors and key business contacts.

"Pitch at Palace Africa 2.0 @hrhthedukeofyork #entrepreneurs #pitchatpalace #london @ktf_key_to_freedom," Ferguson wrote.

Some of Ferguson's followers who attended the event were glad that they did. "Brilliant night, so inspiring!" humanitas_charity commented.

The Duke of York also shared a few snaps of the event on his official account on Instagram. In one snap, he poses with a group of entrepreneurs. Another shot featured Ferguson's ex posing alongside the winners of Pitch@Palace Africa 2.0 including Matibaby, Dext Technology, Cold Hubs and Khainza Energy.

Prince Andrew's first Pitch@Palace event took place on April 2, 2014. The Duke initially worked with 36 businesses across the UK with 12 partner organizations. Since then, the event has progressed.

"We would definitely recommend for any start-up company to be involved. Simply the best pitching event (out of literally hundreds) we have ever attended," Andres Fonseca said about the event.

Ferguson and Prince Andrew remain good friends after they split. In fact, the Duchess has nothing but positive words to say about her ex-husband. In addition, they still share a home at the Royal Lodge, Windsor.

"I'm in and out all the time and he's in and out all the time," Ferguson said about still sharing a home with the prince. "No we're not married - we are very happy the way things are. He is the finest man in my life - he is a nugget of goodness. I threw myself into a love affair for life."

Ferguson explained that her relationship with Prince Andrew and their daughters Princess Eugenie and Princess Beatrice is fine. In fact, she feels that they are "the most extraordinary example of a unified family."

The Duchess also greeted her ex-husband on his birthday. Ferguson took to Instagram and paid a sweet tribute to Prince Andrew on his natal day.

"Happy birthday to the best man, father, friend....Prince Andrew. Feb 19...ooh the best looking," Ferguson wrote on Instagram.
