He's also related to Prince Philip, as his father, David Mountbatten, was his first cousin.
Young Ella delighted royal watchers back in 2005 when she joined Prince William, Prince Charles and the Duchess of Cornwall on the balcony at Buckingham Palace during Trooping the Colour and appeared to thoroughly enjoy the occasion.
Away from the limelight, though, she's carved out a career in community management.

The well-travelled blonde shared pictures from India, Japan, Switzerland, and the Bahamas, as well as locations closer to home, like the Isles of Scilly – also a favourite holiday spot of royal relatives the Duke and Duchess of Cambridge.

Ella is clearly close with her family, posting several photos from her travels with her two sisters.
Lord Mountbatten also shares daughters Alexandra, 21 and Louise, 17, with his ex-wife Penny Thompson, to whom he was married between 1994 and 2011.
He came out as gay after that marriage ended, and in 2018, he tied the knot with airline cabin services director James Coyle in a private ceremony at Bridwell, their Grade-I listed estate in Devon.

Ivar's children were all in attendance, along with his ex-wife, who sweetly walked him down the aisle and acted as best 'man'.
While Ella might not have been able to push the boat out and have a fabulous family party, no doubt her closest relatives will have sent her kind messages for the special occasion.
Well-wishers are likely to include her godfather, the Earl of Wessex, and Alexandra's godmother, the Countess of Wessex.
