Jay-Z To Swizz Beatz: 'Watch Your Son,' After Egypt Kisses Blue Ivy, Alicia Keys Reveals [PHOTOS]

Jay-Z is already being very protective of 1-year-old daughter Blue Ivy, Alicia Keys revealed on "The Wendy Williams Show."

Just days after Keys' halftime performance at the NBA All-Star Game, she headed to the talk show to discuss music and married life. Keys is married to music producer Swizz Beatz, and they have a 2-year-old son, Egypt.

Wendy Williams asked what happens when Egypt and Blue Ivy have play dates, and Keys admitted, “Egypt kissed Blue, and I don’t think Jay liked it very much. He called my husband, and he was like, ‘Watch your son,'" the Daily Mail reports.

But Jay-Z must not have been too upset, as he and wife Beyoncé Knowles greeted Egypt at the NBA All-Star Game.

Over the weekend, Blue Ivy was featured in Beyoncé’s HBO documentary, “Life is But a Dream,” and it was the first time fans really got a look at Blue Ivy’s face, as Beyoncé and Jay-Z often hid her from the paparazzi.

Blue Ivy is already living the good life, as Jay-Z told talk show host Oprah Winfrey last year, "At the end of the day, I just know I'll probably have the worst, most spoiled little kid ever."

The New York Post reported that the rapper spent $600,000 on a solid-gold, handmade horse from Japanese jeweler Ginza Tanaka for Blue Ivy, and Beyoncé and Jay-Z reportedly spent $1.5 million on gifts for their daughter.

Meanwhile, during her interview with Williams, Keys also admitted the best gift Beatz got her.

“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.”

On Sunday night at the game, Keys performed a medley of her hits during halftime, including “Empire State of Mind,” which features Jay-Z, and “Girl on Fire.”

The West beat the East 143-138.
