Ariana Grande creeped her way into the Celebrity Big Brother U.K. house with a surprise video message for her brother Frankie Grande.

Grande's sweet message was part of the Big Brother house's plan to distract contestants with messages from family and friends. Frankie was overjoyed by the video, squirming and screaming in excitement.

“I just wanted to say how much I love you and how proud I am of you,” Grande said, sporting her signature high ponytail. “I’m proud of you for being yourself. I miss you so much and I can’t wait to see you. I have so much to tell you. I have so much music to play you.”

The pop diva’s mother got in on the lovefest, tweeting, “Ariana loves him so much…So happy he saw her message!! #Brother/sister.”

Before his stint on the current season of Celebrity Big Brother -- alongside Danity Kane's Aubrey O'Day and British pop star Samantha Fox -- Frankie Grande competed on Big Brother in the U.S. in 2014.
