Bristol Palin shares baby bump photo at 5 months

Former Alaska Gov. Sarah Palin's daughter, Bristol Palin, shared a photo collage featuring her noticeable baby bump over the weekend.

The 24-year-old is months away from welcoming her second child to the world, although the father is still reportedly unknown to the public.

Palin announced her pregnancy in June, initially calling it a "huge disappointment" to her family. Later, she clarified that she is not disappointed in her pregnancy.

"I do not regret this baby," she said. "This baby is not a disappointment, and I cannot wait to be a mom times two. Tripp is going to make the best big brother!!"

Palin is already mother to 6-year-old Tripp, whose father is former fiance Levi Johnston. In May, she called off her engagement to Dakota Meyer days before their May 23 wedding date.
