Dwayne Johnson proved once again that he's dad of the year.   

The Rock took to Instagram on Wednesday (Oct. 17) to celebrate his six-month-old daughter Tiana Gia's half birthday with a little tune. The adorable baby girl receives her dad's birthday song with some crying, to which Johnson notes that she just wants breast milk. "Don't we all," he cheekily joked.    

"Happy 6 month Birthday to our lil’ disrupter, Tiana Gia. We’re a family of non-traditionalists so we celebrate everything," he wrote in the caption. Tiana is the Rock's second daughter with longtime girlfriend Lauren Hashian, following 2-year-old Jasmine Johnson.
