She is the wife of Gustav, 7th Prince of Sayn-Wittgenstein-Berleburg, making her part of the extended Danish royal family.

They were unable to marry earlier due to a clause in Gustav's grandfather's will preventing him from inheriting family property if he partakes in an unequal marriage (meaning with a commoner).

Axelsson is godmother to Countess Athena of Monpezat, only daughter of her husband's first cousin Prince Joachim of Denmark.

[8][9] In the December 1992 edition of Vogue Italia, she had a 10-page spread styled as Bianca Jagger, shot by German photographer Ellen von Unwerth.

Her experiences in fashion - along with a love of Scooby-Doo and Agatha Christie - inspired her to write the Model Undercover book series.
