Lady Gaga Shares the Stage with Yoko Ono

Having just flown out to the west coast earlier in the day,  Lady Gaga made a special appearance at the Orpheum Theatre in Los Angeles, California on Saturday night (October 2).

Looking her usual eccentric self, the "Alejandro" singer took the stage alongside Yoko Ono to perform with the 'We Are Plastic Ono Band' for a sold-out audience.

Tweeting about the experience, Gaga enthusiastically wrote, "WE ARE PLASTIC ONO. I got to sit in as a guest musician tonight, what a legendary band+mother, Yoko."

Earlier in the day, the 24-year-old boasted about her musical success, as she tweeted, "Today THE FAME spends its 100th consecutive week on Billboard. I wrote it myself + sang it live everynight. Thanku for believing lilmonsters" (celebrity-gossip)
