Jenna Dewan — who’s moved on from ex Channing Tatum and released a new book, “Gracefully You” — celebrated the tome’s launch last week at Mr. Purple.

“It was important for me to share myself, share my story and also share the things and create balance in my life,” she told Page Six of the book. She’s now expecting her first child with boyfriend Steve Kazee.

She wrote in the book of her past, “I had to accept the realization this isn’t working and had moved into hurting.”
