Mariah Carey turned 50 years old on Friday (March 27), and Britney Spears took to Instagram to honor the pop icon who inspired her.

"Happy Birthday @MariahCarey !!!!! You are one of the main reasons I started singing ...." she wrote alongside a sweet photo smiling with the chanteuse at a restaurant. "your Butterfly album never gets old even after 20+ years ….. it’s simply a classic and I will be listening to it today as I work out in the gym !!!!! Have a wonderful birthday !!!!!! God bless."

The birthday girl saw the sweet wishes and gave an equally loving response. "Love you Britney!!!" she wrote alongside red heart emojis. "And I'll be listening to Stronger as a moral booster! Thank you for this beautiful message."

Earlier in the day, Carey celebrated her birthday by sharing a photo in the studio. "Starting 3.27 with a new song," the superstar wrote alongside a grinning selfie on Twitter, using the hashtag #stayhome amid the coronavirus crisis.
