She recently appeared to bury the hatchet with her old feud-mate Taylor Swift.
And on Sunday, while Taylor was in Las Vegas to win two Billboard Music Awards, Katy Perry was heading to work in Los Angeles.
Katy, 33, held her teacup poodle Nugget as she arrived at the studio to tape American Idol, which she is reportedly paid $25 million to judge.

Later on, this time without Nugget, she was glimpsed outside in the feathery wrap and platinum blonde wig she had donned for the episode.
When she first turned up at the taping, she teamed a grey hoodie with matching sweats, accessorizing with sunglasses and a bubblegum pink baseball cap.
Her high-camp look later on featured gold floral embroidery over her sheer sleeves, as well as a sky blue ribbon tied into a bow at her neck.

On that night’s episode, the first of a two-part season finale, Katy dismissed the opening performances by the three finalists as ‘a disaster.’
But the star proved she isn’t harsh as she might appear over the weekend, as she treated fans at her hometown Santa Barbara concert to a free drink.
The benefit show aimed to raise money to help relief efforts for the wildfires and mudslides that struck the area earlier this year.

But video footage shows concert-goers were a little bit too excited by her generous offer as they were caught slipping off to the bar midway through her performance, prompting Katy to desperately try and call them back.
At the Billboard Music Awards at the MGM Grand Garden Arena Sunday night, Taylor picked up trophies for Female Artist and for her new album Reputation.
Earlier this month, Taylor shared a social media post thanking Katy for a literal olive branch the latter had sent over, seemingly to end their squabble.
The battle of wills was rumored to have started with a dispute over backup performers years ago – in a 2014 Rolling Stone interview, Taylor accused a female star she wouldn’t name of attempting ‘to sabotage an entire arena tour’.

‘She tried to hire a bunch of people out from under me,’ said Taylor in the cover story, referring to herself and the other woman as ‘”straight-up enemies.”‘
The day after that Rolling Stone interview hit the Internet, Katy tweeted: ‘Watch out for the Regina George in sheep’s clothing…,’ in a nod to the vicious school bully played by Rachel McAdams in the 2004 film Mean Girls.
Katy struck a defiant tone when she appeared in the Carpool Karaoke segment of The Late Late Show With James Corden, airing last May.

Saying of the ‘situation’ that Taylor ‘started it, and she’d better finish it,’ Katy admitted: ‘It’s about backing dancers!’
Katy released her album Witness in June – and that same day, Taylor restored her back catalog to streaming services after having withdrawn it in November 2014.
Taylor was widely regarded as having timed this streaming release specifically to siphon publicity away from Katy and damage her album sales.
Whether or not Taylor’s gambit actually had any impact on Katy’s success, Witness did indeed prove to be a flop both critically and commercially.

Taylor, whose 2014 song Bad Blood is rumored to have been about Katy, released Reputation last November to considerable success.
In the music video for Reputation’s score-settling lead single Look What You Made Me Do, she makes a not-so-thinly-veiled dig at her brunette nemesis.
At one point, Taylor is dressed strikingly like Katy while crashing a car and emerging from the wreck brandishing a Grammy Award.
Katy was infamously a 13-time Grammy nominee and a zero-time winner, while Taylor had won a grand total of 10 Grammy Awards by that point.
