The Prince of Wales made an unexpected appearance in Monaco on Tuesday, where he was seen with Thomas van Straubenzee, one of his closest friends and Princess Charlotte’s godfather, watching Aston Villa play in the Champions League.

After the Premier League team lost 1-0 at the Stade Louis II, Prince William appeared thoughtful as he was unable to improve the fortunes of his beloved team.

Television cameras captured the heir apparent sitting in the principality, dressed in a sweater over a blue shirt and a blue jacket.

Hours after his appearance at a charity in London, he was rubbing his hands together and looking icy as he talked to a man next to them and his close friend Thomas in the stands.

Since they both went to Ludgrove Prep School together, the two have known one another for a long time.

After being married to Lady Melissa Percy from 2013 to 2016, Mr. van Straubenzee is currently married to Lucy Lanigan O-Keeffe, Princess Charlotte’s former St. Thomas’s Battersea teacher, with whom he has two children.

William is the godfather of his daughter, Mary.

Prince Albert of Monaco was also seen cheering on his own team during Tuesday’s game, accompanied by Dmitry Rybolovlev, the club’s owner and president.

Last October, when his team defeated Bayern Munich earlier in the competition, the Prince of Wales was spotted in the stands.

In a rerun of their European Cup final victory, William was seen on TV hugging and cheering his teammates as they defeated German powerhouse Bayern 1-0 at Villa Park.

When Aston Villa supporters gathered before a midweek game in Birmingham last week, the prince went there and had a beer with them.

In the heart of Birmingham, the group met up at a Wetherspoons pub after William asked his club to set up the meeting with some supporters.

Ahead of an away game against Everton, the future king gathered with eight fans around a set of tables to talk about their favorite team.
