Beyonce and Jay-Z shared an interesting moment Tuesday night (May 8) as the rapper pinched his superstar wife’s cheeks — the ones on her face, of course — at a party hosted by L.A. Reid celebrating the launch of his wife Erica Reid‘s new parenting book “The Thriving Child.”

R&B singer Mary J. Blige and Beyonce’s mother Tina Knowles were also on hand for Erica Reid’s book launch, which was held at a private residence in New York City.
