Jessie J disses Rihanna on Twitter

Jessie, who seems to be tired of the 'Umbrella' hitmaker's endless self-promotion, recently pointed her finger at the star's irritating Instagram account during a rant on Twitter, reported Sun Online.

"I'm bored... Maybe I should get naked and smoke and take pictures of myself and post them on instagram? Or NOT... Rolls eyes," Jessie tweeted.

When fans responded in agreement, 'The Voice' judge backtracked by saying that her tweet wasn't aimed at any one person in particular.

Jessie then sent another tweet, "I'm going to be honest. My tweet about instagram was NOT aimed at anyone in particular."

"But I will openly say the amount of pictures including men and woman nude and girls and guys promoting smoking drugs on the internet these days is a lot. Feels like the boundaries are disappearing. It's become fashionable and in my opinion it is too much. Call me what you want but that's MY opinion and I'm entitled to one," she added.
