Jay-Z and Beyonce spent an evening with friends Tuesday night (May 8) in support of author Erica Reid's book launch for "The Thriving Child." The event, hosted by Erica's husband and music executive L.A. Reid, brought out Bey's mom, Tina Knowles, and singer Mary J. Blige, among others.

During the festivities, Hov showed his wife public affection by squeezing her cheeks. The act was fitting, considering Beyonce gushed about their daughter Blue Ivy's own facial features at the book launch. "She's four months old today, and she's just got the most delicious little cheeks," the 4 songstress noted.


"The Thriving Child: Parenting Successfully through Allergies, Asthma and Other Common Challenges" explores the allergy battles Erica's own children have faced and how she's coped as a parent by introducing re-vamping her family's diet and detoxing her home. The book also includes in-depth prescriptive advice from top experts, including doctors and celebrity mothers.

This week has been a busy one for the 30-year-old entertainer. Beyonce graced the red carpet at the Metropolitan Museum of Art Gala in New York wearing a Givenchy Haute Couture gown by Riccardo Tisci. The dress was not only eye-catching but daring for the singer since its flesh-colored pieces revealed some of her voluptuous body parts.
