Chris Brown is apparently letting his daughter scribble and play on his expensive cars. Rihanna's former boyfriend is embracing his responsibilities as a father and taking care of Royalty.

"Chris is known for his ultimate car collection and for keeping them clean as a whistle – not anymore," a source told Hollywood Life. "Royalty's turned one of his rides into her school on wheels. The backseat is filled with her toys, crayons and colouring books. But instead of colouring in the books, she likes to take her pen and create on his leather seats! And surprisingly, he lets her!"

"He thinks [Royalty drawing on his car] is a form of expression and at the end of the day, he can replace those seats," the insider added. "There are also customised TVs in the headrests of one of his SUVs so Royalty can watch her edutainment shows. Chris has a slew of edutainment DVDs in his SUV. There's alphabet songs, number riddles and this cool little rhyme that these animated beavers do as they rap about all the different shapes and colours."

"Chris loves singing along to one of the alphabet songs with Royalty," the source continued. "It's the most precious thing ever. And whenever she counts to five on her fingers, he looks at her in the mirror on his windshield, smiles at her and gives her the biggest kiss ever. When he does that to her, she giggles, and covers her face with her hands."

Earlier this year, the Say Goodbye singer discovered that he was a father to a little girl. Following that, Karrueche Tran announced her split with Brown by declaring she did not want "baby drama". In August, Brown had lashed out at the mother of his child, Nia Guzman, for allegedly using Royalty, as a "meal ticket".
