Stars turned authors: Kim K. and J Lo in a show of celeb sisterhood

Kim Kardashian is plugging Jennifer Lopez's brand-new memoir, True Love.

And guess who spotted her toting it around in New York City while out with Kanye West?

Not the paparazzi but J Lo herself!

Here's what the star tweeted yesterday afternoon (Nov 7).

Lopez has been jetting about promoting the book, website E! Online reported.

It seems she's also busy talking about ex Ben Affleck, whom she called her "biggest heartbreak" in the book.

She said in an interview: "I really felt like I had found somebody great and he had found somebody great and we thought we could make it work."

Lopez said of her "totally single" status: "It's not going to be forever. Someone great will come along."

She's not the only author on the block - Kim has her own book coming out too.

Titled Kim Kardashian: Selfish, it will be on shelves next year on April 28.

The publisher's note hails Kim as "one of the most iconic celebrities in the world".

"Hailed by many (including Givenchy designer Riccardo Tisci) as the modern-day personification ofMarilyn Monroe, Kim has become a true American icon."
