Brooke Mueller celebrated her birthday with twins Bob and Max ... and you could see the wheels turn as she made a wish before blowing out the candles.
Brooke was at the L.A. Zoo with the 4-year-olds she had with Charlie Sheen, when everyone stopped for a makeshift birthday celebration. The video was taken in August, just after she lost custody of her kids.
It's an interesting peek. By the way, watch one of the twins as she tries talking to him.
