Rihanna cringes over her mother'

We've all had that red-faced moment when our mothers joke about our love lives in public.
Rihanna suffered the same fate last night when her own, Monica Braithwaite, chose the Time 100 Gala - an esteemed event honouring the 100 most influential people in the world - to discuss her daughter's headline-making alleged fling with Ashton Kutcher.
A cringing Rihanna told fans of her embarrassment by tweeting about the goings-on at the party: 'Well....2nt consisted of us singing Bob Marley, drinkin Vintage Scotch, and my mom thinkin a joke abt Kutcher was appropriate! #Thxtime100' (sic).
