It's not just reporters annoying Rihanna with references to a late night with Ashton Kutcher -- it's also her own mom!
The sexy singer stunned in fuchsia on the red carpet at Time's 100 Most Influential People In the World gala on Tuesday night, an event she attended with her mother Monica Fenty and grandfather Lionel Brathwaite.
While the group looked happy in photos, Rihanna was clearly annoyed when her mother cracked a joke about the "That '70s Show" star.
After the event, RiRi tweeted "Well....2nt consisted of us singing Bob Marley, drinkin Vintage Scotch, and my mom thinkin a joke abt Kutcher was appropriate! #Thxtime100"
Who else is dying to know what Monica said to her?!
Rihanna was hardly the only celebrity in the room -- as the party was also attended by Amy Poehler, Tyra Banks, Tilda Swinton, Kristen Wiig, Claire Danes, Chelsea Handler and Hillary Clinton ... who took pictures with EVERYONE.
