They did it for their son! Mashonda and Swizz Beatz (minus Alicia Keys) got together to celebrate Kaseem Dean Jr. birthday, who turned 4 years old. Lil man looked so adorable at his music themed party. This is when parents show their maturity. I applaud them for making Kaseem’s day extra special with BOTH his parents present. We’ve got the exclusive images of his amazing day right here! Don’t forget to leave us you thoughts and opinions below.
