10 of the youngest celebrity grandmothers (+Photos)

3. Sarah Palin

Sarah Palin is best known for running for vice president a few years ago as part of the Republican party. She’s made some pretty…interesting comments during interviews and press conferences, and has even been spoofed on Saturday Night Live by Tina Fey (the two actually look a lot alike). In 2008, when she was 44, Sarah Palin gave birth to her youngest son, Trig. That same year, her 18-year-old daughter Bristol, revealed that she was pregnant. In Bristol’s memoir, she reveals that her mother thought she was playing a practical joke on her when she told her mom the news. In December of 2008, Palin, now 51, became baby Tripp’s grandmother. Bristol will be welcoming another child in this year.
