She was able to share in the celebration with her children Ava and Deacon, along with her parents.
"It's really emotional," Witherspoon said. "My mother was reminding me that this is my 20th year of making movies. I started when I was 14 years old growing up in Nashville, Tenn. It feels like an incredible honor to make it from Nashville to Hollywood Boulevard."
James L. Brooks, who directed Witherspoon's next movie, also attended and told the crowd she really does deserve the moniker "America's Sweetheart."
"That's who she is to me," Brooks said. "Yes, world-class actress and capable of dishonesty on the screen, and from what I've seen -- no kidding -- in life as well. She is a natural, on screen and off. Just naturally an amazing mother and daughter, and person and American citizen."
