Wiz Khalifa is in the process of building his child custody case against his estranged wife Amber Rose.

Earlier this week, we shared the news that he wants to spend more time with his son Sebastian and claims Rose is a bad mom due to her partying ways. The rapper now has photos of her home, which support his assertions that the residence is too dirty for their 1-year-old.

TMZ shared several photos of the home, indicating feces around what appears to be a patio area. In documents creator by Wiz, he claims that the dog eats its own feces, then lick their baby's face.

Other photos show overflowing garbage cans and a knife being left on the kitchen counter. Reportedly, the platinum-selling rapper will use these photos as evidence to support his case.

Meanwhile, Amber is enjoying herself in Trinidad for Carnival. She posted a few eye-catching videos of the festivities on her Instagram page. The 31-year-old has reason to celebrate. She will release a new book, How to Be a Bad Bitch, later this year. According to Billboard, she'll give advice on fashion, money, love, beauty and achieving high self-esteem.

"[How to Be a Bad Bitch is a] self-respecting, strong female who has everything together," she said in a statement. "This consists of body, mind, finances and swagger; a woman who gets hers by any means necessary."

Gallery Books is publishing Amber's book. Vice president and publisher Jennifer Bergstrom says many women will connect with her reality on paper. "Amber Rose is the ultimate cool girl who you want to be best friends with," she said. "I know a lot of women who will want to read this book."

In the meantime, Wiz is forging ahead with his custody battle. You can see the photos of Rose's home by clicking on the TMZ link above.
