Bristol Palin brought her son Tripp to her Dancing with the Stars dance studio Saturday and the toddler proved to be a real ham with photographers.  Just take a look at these photos on Breaking Celebrity News.

Bristol, 19, had her 21-month-old son with her as she arrived for rehearsals with dance pro Mark Ballas, and the adorable little boy instantly smiled, laughed and waved to photographers.

Tripp is living with his mom in Los Angeles during her stint on Dancing.  She shares custody with ex-boyfriend Levi Johnston.
