Princess Catherine (aka Kate Middleton) is stepping out for the first time following the arrest of uncle-in-law Andrew Mountbatten-Windsor (formerly known as Prince Andrew).

The 44-year-old Princess of Wales was all smiles as she attended the England vs. Ireland Six Nations Match on Saturday (February 21) held at Allianz Stadium in London, England.

Kate, who appeared as Patron of the Rugby Football Union, wore a navy coat over a black turtleneck paired with a England Rugby scarf.

She was seen in stands speaking to injured England player Fin Baxter and RFU President Deborah Griffin.

Days earlier, Kate‘s husband Prince William‘s uncle Andrew was arrested on his 66th birthday amid the ongoing controversy regarding his connection to Jeffrey Epstein.

Andrew was taken into custody on suspicion of misconduct in public office, as authorities investigate claims that he shared British trade info with Epstein in 2010.

Many are wondering about what is next for ex-Prince Andrew, and we have some more details, including how much jail time he could face.
