“Russell who?” is exactly what recently divorced Katy Perry was probably asking herself while she made out with her new boyfriend, Florence + the Machine guitarist Robert Ackroyd over the weekend at the Coachella Festival.

Eyewitnesses say the new couple couldn’t keep their hands off each other, and made no attempt to attempt to hide their lust for one another as they put on a show of PDA for the Coachella crowd.

The 27-year-old “Part of Me” singer rocked a pair of high-waisted shorts with a matching sheer blouse, while Ackroyd wore a white tee and jeans. When they weren’t kissing or making googly eyes at each other, Perry and Ackroyd either held hands or held each other in a close embrace.

Take a look at the loved up pair in the pictures below:

Rihanna sure does know how to party, and the Pop singer looked like she was having the time of her life while enjoying (and partaking in) the 2012 Coachella Festival in California this past weekend.

During Day 3 of the weekend-long concert festival in Indio, CA, Rihanna surprised fans when she hit the stage with DJ Calvin Harris and the two performed their “We Found Love” single.

Rihanna also performed her latest single “Where Have You Been,” and she spotted her BFF Katy Perry in the crowd and went crazy with her and a group of fans in the audience.

Right before that, a purple-haired Katy Perry stag dived into the crowd and crowd-surfed across the audience as Rihanna and Calvin Harris were performing.

Later in the night, Rihanna was spotted rolling up a blunt in the crowd before hopping on top of her bodyguard’s shoulders to take in the rest of Calvin Harris’ concert set as she puffed on her “cigarette.”

Tupac made the ultimate return to life last night at Coachella.

During Dr.Dre and Snoop Dogg‘s set at the 2012 Coachella Valley & Arts Music Festival in California, Pac was resurrected on the stage via hologram and performed a couple of his greatest hits, including “Hail Mary (Come with Me)” and “2 of Amerikaz Most Wanted,” (with Snoop Dogg).

At the end of his short performance, a light shined on Pac and his virtual image disappeared into thin air.

Watch the historical occasion below:

After a few technical hiccups, R&B singer Frank Ocean performed his own solo set live on stage at the 2012 Coachella Music Festival in California.

Despite the malfunctions, Frank still put on a great show during his 30-minute plus set, which included performances of his most popular songs, like “Swim Good,” “Novacane,” “Thinking About You” and more.

Frank Ocean even brought out his Odd Future bandmate Tyler the Creator for a quick performance of their collaboration song “Analog 2″ from their “Odd Future Vol. 2″ mixtape.
