Since Richie posted the video to her Instagram, she has received over 15,000 comments. One of which was from her brother-in-law Benjamin Madden, who made a little joke about the incident, “Happy Birthday Sis love you and thankful for you always stay lit.”
Richie is married to Madden’s brother, Joel.
CNN has reached out to her representative for further comment.
