Congrats to Sarah Stage! (a.k.a the Six Pack Mum)
She first became famous in 2015 after the world couldn't believe how she had such a toned body and be pregnant at the same time:
Earlier this year Sarah announced that she and her partner were expecting for the second time saying:
We'd been trying to conceive for several months, I couldn't imagine not sharing the news of my pregnancy with my followers.
This week she's gaven birth to her second baby boy, with her husband Kris Jason, and named him Logan Alexander.
The couple spoke to E! News after the pregnancy saying "We are so overjoyed and happy to welcome baby Logan into our family."
Another member also added "Sarah, husband Kris and baby Logan are resting. Sarah delivered Logan this afternoon and is resting with new baby per the Doctors orders. Her toddler James is with family, has met his baby brother and the family is very excited. Sarah and family thanks everyone for their overwhelming amount of support, and promises everyone will get to see baby Logan soon."
