Ryan Seacrest and Julianne Hough
06/15/2012 at 01:00 PM EDT
declared her love for boyfriend Ryan Seacrest
on his radio show Friday – but Seacrest didn't say it back.
Hough, 22, called in as a guest on Seacrest's KIIS-FM radio show
to promote her new musical movie, Rock of Ages
, which opens Friday.
Seacrest said he "loved" the movie and praised his girlfriend throughout the eight-minute interview, which was full of sweet, giggly moments
between the lovebirds.
As the segment came to an end, Seacrest said, "I'm very proud of you. Go see Julianne in the movie. Thanks, darling."
Hough answered, "Alright. Love you. Bye." To which Seacrest simply answered, "Bye."
After Hough hung up, several staff members on the radio show could be heard chastising Seacrest. "She said 'I love you' and you didn't say it back!" they yelled.
"Because you guys won't shut up," Seacrest teased before signing off for a commercial break.
