Today is Single Parents' Day! It's a holiday devoted to celebrating the hard work that single parents put into raising their kids. In case you didn't know, a bunch of stars have been raised by single parents under different circumstances. This is why it's the perfect time to recognize the famous people who have lived in one-parent households (if not permanently, at least for a little bit) — and honor the wonderful support systems that helped them thrive.
