Happy Birthday, Olivia Allison! May your day be as perfectly synchronized as your incredible routines at the 2008 Beijing Olympics. We still marvel at how you gracefully danced underwater without losing count or breath—skills most of us can't manage even on dry land!Your Olympic debut remains unforgettable, and we're convinced you're secretly part mermaid. Here's hoping this year brings you more success, laughter, and fewer nose clips lost in the pool. Keep making waves both in and out of the water; you're truly an inspiration (and a splash) to us all! Have a fantastic birthday celebration, Olivia!
