18-year-old Bristol Palin gave birth to a son who will carry on the Palin tradition of strange names. Tripp Easton Mitchell Johnston was born Sunday at 7 pounds, 4 ounces, People says. Colleen Jones, the sister of Bristol's grandmother, told the magazine that "the baby is fine and Bristol is doing well."

The baby's arrival is probably welcomed good news after three bad months for the Palin and Johnston families. When it was announced shortly after Gov. Palin was named John McCain's running mate that her teenage daughter was expecting, it triggered national debates on teen pregnancy and marriage, abstinence education, the VP vetting process, the privacy of political families and, well, just about everything.

Bristol Palin is 18, as is her boyfriend of three years, Levi Johnston, a former high school hockey player. Both have dropped out of high school -- she to complete her diploma through correspondence courses, People reports, and he to become an apprentice electrician, he told the AP this fall. They have said they plan to marry in 2009.
