In two of the intimate pictures, Nikki Bella stood completely topless in front of her bathroom mirror. She covered both of her breasts with her right hand while she is clicking a mirror selfie from the left hand, giving her millions of followers Botha. Front and side view of her growing belly.

"There is my love. 18 weeks tomorrow," she captioned one of the pictures that she shared on her Instagram handle. In another picture, she got candid about her body and talked about her struggle with retaining so much water.

"It's crazy because a day after workouts abs really pops out in the morning. But the thing I am dealing with is retaining a lot of water throughout the day. I will not look like this tonight. I cannot believe how much I retain in a day," Nikki added. "Obviously boobs have gotten huge." In the subsequent video, Nikki talked about the gray hair and why she is freaking out.

"Look at all my greys. Can you see them? I know you can get your hair dyed when you're pregnant but I feel like I'm losing my hair, jeez. I'm freaking out, that's sad. I maybe need to dye my hair now," she said. You can check out Nikki Bella's topless pictures here.
