"Nine months pregnant and no stretch marks on my body," Wiz Khalifa's fiancee tweeted along with a picture of her bare baby bump shortly before son Sebastian was born. "Thank you Jesus!" Later, she tweeted about the special -- at times painful -- bond she shares with Bash. "Breastfeeding is awesome. It kinda hurts though," she confessed. "But the bonding with my baby is unbelievable. So worth it."
