On Friday, the American Idol star was surprised by friends, who made her decipher a clue spelled out with Scrabble letters, which revealed she was heading on a girls’ trip with her pals, mom and sister. It looks like the group ended up in Florida, with Clarkson’s 1-year-old son, Remington, and 2-year-old daughter, River Rose, along for the fun.

“Thank you @universalorlando for the most magical birthday!!!,” she wrote. “It was the greatest surprise to have my entire group adorned in Harry Potter gear!!!
