AceShowbiz - Selena Gomez adores Britney Spears as much as the "Toxic" hitmaker adores her. The "Only Murders in the Building" actress admitted to feeling "speechless" after the 40-year-old pop star said the former Disney star was a "beautiful surprise" at her wedding.

On Saturday, July 16, Britney posted a dedication to Selena by sharing Selena's photo that saw her posing in a khaki jacket with a cropped waist and a skirt made out of an airbrushed white shirt that read "happy" and writing a long caption singing her praises. "She came to my wedding … the three most beautiful women in hollywood … @drewbarrymore, @parishilton … I had no idea !!! I was SO HAPPY !!!" Britney began.

"[Selena] told me 'I just want you to be happy' three times ... My mother does that as well … It was so cool she was able to get to me and share her thoughts," Britney continued. "Although I've been forced to see people against my will my whole life ... she was a beautiful surprise !!!"

Britney went on to add, "I appreciate ALL the mental health speeches she does for our generation." The "Baby One More Time" hitmaker further gushed, "You're such a special person and I had to share this picture … I thought it would make her happy !!!" before concluding her post as writing, "Selena, I'm so happy to have such a supportive family !!! God bless you [red heart emojis]."

In response, Selena commented in the comment section, "I'm speechless. Britney-you are so kind and have the most beautiful soul." The 29-year-old singer/actress went on, "I am beyond lucky to know you. You deserve all the happiness in the world!"

Selena attended the wedding of Britney and Sam Asghari on June 9. She even shared a photo of herself with the bride, Paris Hilton, Madonna, Drew Barrymore and Donatella Versace via Instagram Story. In a note accompanying the snapshot, she penned, "Congrats Britney!! So honored to have been part of your wedding day. Love you!!"
