She famously ruffled feather when she became the wife of one of rock's most famous sons.
But Yoko Ono, 77, is no match for the towering pop colossus Lady Gaga, 24, who overshadowed John Lennon's widow as they took to the stage in Los Angeles last night.
The singer wore a typically cheeky outfit - a bejewelled catsuit - which deliberately exposed her bottom.

And Gaga made no concession to the petite Japanese musician and artist as she teetered around the stage in a pair of super-high platform boots.
Wearing a crystal studded black bodysuit and spiked headband, it was, one might say a more sober look than usual for the outrageous singer whose stage shows often require her to be soaked in fake blood.
Gaga joined with the Plastic Ono Band,formerly a loose supergroup of musicians that Lennon assembled 40 years ago.
Lennon's widow was excited to be performing again, she said: 'I have never done a show in L.A., so I am very happy to be finally doing it.'

The occasion came ahead of a series of celebrations for the music legend who would have turned 70 this week!
Last night's rejuvenated version of the Plastic Ono Band also included Yoko and John’s son Sean Lennon as well as Thurston Moore and Kim Gordon of Sonic Youth.
The Alejandro singer and Ono performed in front of a sold-out audience, and Ono looked slightly in awe of the eccentric star.
Gaga tweeted: '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.'

Events has been ongoing in Hollywood over the last week honouring Lennon’s 70th birthday.
The film about Lennon's youth, Nowhere Boy by Sam Taylor-Wood, starring Aaron Johnson, premiered at the Egyptian Theatre last Thursday, with a performance by John's original band, the Quarrymen, during intermission.
Tonight Ono will sit down for an intimate interview about her husband and his legacy in the Grammy Museum’s ongoing series, 'An Evening With.'
The museum will also unveil its new exhibit, John Lennon, Songwriter, which will open to the public on Monday.
The exhibit was co-curated by Ono and includes many personal artifacts including hand-written song lyrics, original drawings, guitars, a Sgt. Pepper outfit and rare historic footage.

While tomorrow night the museum is hosting the West Coast premiere of the documentary film American Masters: LennonNYC, with Ono in attendance.
The film focuses on their life together in New York and will be broadcast on PBS Nov. 22.
There will be a Proclamation issued by the City Of Los Angeles and a Council Resolution by the L.A. Council, both saluting Lennon for his cultural contributions to Los Angeles.
The exhibit is curated by Beatles scholar Martin Lewis and Rod Davis of The Quarrymen who are travelling the country to pay homage to their friend and former band member.
And Gillian Lomax's Magical History Tour will take you on a 3.5 hour tour around the Beatles' old haunts in L.A. They are on Sundays and are $65.
