Alicia Keys appeared on the Wendy Williams show on Monday to reveal some special news about Beyonce Knowles and Jay-Z's daughter, Blue Ivy.

Keys shared on the show that her son Egypt often plays with Blue Ivy and during one play date, her son kissed the 1-year-old toddler. The singer recalled, "Egypt kissed Blue, and I don't think Jay liked it very much. He called my husband and he was like, 'Watch your son.' "

Blue Ivy appeared in her mother's documentary Life is But a Dream, which debuted on HBO on Feb. 16. In the no-holds barred film dedicated to Blue Ivy and Jay-Z, Knowles shared her first ultrasound and a very intimate moment when she felt her daughter kick inside her belly for the first time.

A photo was leaked Friday showing Knowles flashing a huge smile all the while holding Blue Ivy, according to E!. In the documentary, Blue Ivy's journey into the world is recorded and she also appears in the film being cradled in Knowles' arms.

Like Knowles, who revealed in several interviews that she plans to have more kids, Keys said she's pretty much sure she wants more children at some point.

"I definitely want more kids... I would like to wait at least two years," she said. "I do actually want more children and sometimes I think it does feel like, 'Oh man, what if I could just spend every waking minute with Egypt,' Of course I would love to."

During the interview, Keys also revealed one of her best gifts she received from her husband, Swizz Beatz.

"This might sound strange but I think the favorite gift he ever got me [was] he got a tattoo of me on his arm. Of my face. He hid it. It's so beautiful. He mixed it with some of his favorite artists...It's so pretty"
