Today on Twitter, Katy Perry announced that English singer-songwriter Ellie Goulding will be joining Perry on her California Dreams tour! Unfortunately, Goulding is replacing Jessie J, who recently broke her foot and will not be able to join in on the California Dreams fun! The singer, who recently appeared as the house artist at the MTV VMAs also tweeted her disappointment over not being well enough to go back out on tour! Maybe next time, Jessie! Rappers Royce da 5'9'' and Big Sean were tweeting about the big fight between Ray J and Fabolous, but taking two very different stances on the incident. Lea Michelle sent her congratulations to the 2011 Emmy Awards host (and co-Glee star) Jane Lynch while Wiz Khalifa had some mushy-gushy words for his boo, Amber Rose. See what your favorite stars were chirping about today!
