"We’re celebrating Summer Rain all week... and Leo lioness energy all month," Aguilera, 40, announced on Instagram. "Happy 7th birthday my sweet, thoughtful, funny, creative, soulful, vibrant spirit."

"Time moves too fast but every year I’m so in awe of the beautiful human you are and continue to grow to be," the proud mom continued to gush. "You are so loved by all around you and inspire us to see the world brighter because of you and the special energy you radiate!"

"Mommy loves you so much," Aguilera concluded, spamming unicorn, heart and party-themed emojis.
