While that headline may look like it came from a random music news words generator, it is in fact true.
It turns out, the recent Oscar winner rocked up at the Limp Bizkit frontman's regular weekly jazz night in Los Angeles on Thursday, grabbed the mic and delivered a couple of songs by Ol' Blue Eyes himself.
“I’m here to ruin the party," she joked, as Entertainment Tonight reports.
Gaga performed Sinatra favourites Fly Me To the Moon and Call Me Irresponsible at the Black Rabbit Rose venue. She’s apparently been performing both tracks lately at part of her Las Vegas residency.
Introducing the latter she quipped: “My whole life, you know, I’ve been called irresponsible.
It doesn’t make me so mad because it’s kind of true… and I like to hear the truth.”
You can find some footage online but be warned about any potential jazzy language.
Lady G has dismissed tabloid reports she's pregnant with confirmation that they only thing she is expecting, is to finish her sixth album.
The singer/actor recently won an Oscar for best song for Shallow from the movie, A Star is Born - which she also starred in, alongside Bradley Cooper.
Their intimate performance of the track also set tongues-a-wagging and she denied they were having an affair on US TV.
Now, her fans aka the Little Monsters, will be delighted to learn that the only thing she is planning on giving birth to is the follow-up to 2016 LP Joanne.
We wonder if she's already picked out a name?
Lady G flaunted her Oscar during an appearance on the Jimmy Kimmel show last night.
The trophy - which she won for best original song for Shallow, from the movie A Star is Born - even came with its own undies.
The big talking point though was her red hot piano performance of the track on the night alongside co-star Bradley Cooper, which was so heated that many online decided it must be a real-life romance.
Turns out they just acting out the story - simple as that.
After rolling her eyes at the suggestion the two were having an affair, Gaga said: "Social media, quite frankly, is the toilet of the internet and what it has done to pop culture is abysmal.
"And yes people saw love, and guess what... that's what we wanted you to see!
"This is a love song... the movie, it's a love story."
She added: "Fooled you!"
To drive home the point Gaga confirms she wasn't secretly seeing octogenarian Tony Bennett either when they made an album together in 2013.
Looks like Lady G enjoyed her night, after bagging one of the big musical awards on Sunday in Los Angeles.
And why not?
The singer, whose track Shallow took the best original song award, was found - by Time magazine's well placed photographer - sharing a loving snuggle with the Queen of Pop, Madonna.
According to Rolling Stone mag, the pair have previously endured a frosty relationship due to claims Gaga has borrowed some moves and looks from Her Madge but that all seems to be water under the bridge now.
"Don't mess with Italian girls," warned Madonna with reference to their shared heritage in the caption to the above picture.
Fun fact: Singer/actress Madonna has never won an Oscar.
Check out more backstage images including Gaga with Shallow co-writer Mark Ronson, as well as Ashton Kutcher and Mila Kunis, Ibeyi and Swae Lee enjoying a cigar.
As well as earning her a nifty gold statuette to place in her bathroom, the Academy Awards have also given Gaga a considerable sales boost.
According to US chart analysts Nielsen Music, Shallow sold nearly 21,000 downloads on Sunday (up 121 percent).
Another man with reason to celebrate was Rami Malek who bagged best actor for his portrayal of late Queen singer Freddie Mercury in the biopic Bohemian Rhapsody.
Let's hope that wasn't a hired suit he was wearing as he sprayed Champagne everywhere (especially after falling off stage).
If we hadn't reached peak Queen already, then fans might be interested to note that a new documentary entitled The Show Must Go On: The Queen + Adam Lambert Story, will debut on ABC on Monday 29 April.
