Note to celebrities who bring their parents along to events: They like to talk and tell all the juicy details of your love-life.
Case in point: Rihanna brought her mother, Monica Braithwaite to the Time 100 Gala at Lincoln Center on Tuesday night where she dished on Rihanna's late night romps with Ashton Kutcher last month.
Rihanna tweeted about the incident:
"Well....2nt consisted of us singing Bob Marley, drinkin Vintage Scotch, and my mom thinkin a joke abt Kutcher was appropriate! #Thxtime100."
