She is also the mother of the current Emir of Qatar, Tamim bin Hamad Al Thani, 43, who additionally has three wives.
She wowed royal fans at Crown Prince Hussein of Jordan’s wedding wearing a custom Maison Valentino Fall/Winter 2021 couture gown in bright neon green.
She accessorised with a matching neon green veil and a bejewelled belt around her tiny waist.

Moza looked incredible wearing bold light red lipstick and heavy makeup, and she also carried a silver clutch bag.
Royal fans took to social media to praise the Sheikha, with Instagram user @thedonn884 saying: “It’s amazing that even standing with ladies all wearing jewelled tiaras – she just radiates power and grace.”
Social media user @virtuemoirfan added: “Sheikha Moza always owns her looks – she wears the clothing and never the other way around.
“Fierce woman. I miss seeing her at events like she used to go to. She’s probably the only woman who can take a runway concept style and make it her own.”
Royal watcher @kehsusana commented: “She has powerful, strong and fierce vibes in a good way – like she has an amazing sense of style.”
Another fan, @giosussinna wrote: “The colour of that gown is really surprising and makes her look so stunning! Great choice of accessories too.”
Similarly, @gringa_andante said: “She’s radiating power.” @hvflaherty added: “How is she almost 64 years old? She looks stunning.”
Royal fan @ale_campos_gua commented: “Her elegance is unmatched! This is a tough colour to pull off, but she nailed it!”
One social media user @ess2195 wrote: “Love Sheikha Moza’s style! The lime green Valentino dress shines on the Jordanian royal wedding as magnificent.”
The mother of seven’s family, who is unknown to most Britons, owns the Olympic Village, Harrods, and the Shard. More of London is owned by her state than by the Crown Estate.
Sheikha Moza has been called “among the most elegant women in the world” because of her flair for fashion.
She was included in the International Best Dressed Hall of Fame List by Vanity Fair in 2015, and her Instagram account has at least £1.2million followers.
