The two held hands while leaving Barnes and Noble, all while smiling for the flashing cameras of the paparazzi.
Willow showed the highest honor to her father by tweeting a special birthday message that melted our hearts.
The "21st Century Girl" singer tweeted, "He's the light of my life, Happy Bday Daddy <3"
As for her career, Willow is almost finished with her album and one of her producers Ronald "Jukebox" Jackson, can't stop talking about the song she did with GlobalGrind's general and the new Mr. 106 and Park himself, Diggy Simmons.
Jukebox told MTV, "It's getting very great reaction. We also did a record with Diggy Simmons that's incredible."
We know that's going to be a banger for sure. The future of music is in good hands with these two!
