Independent Spirit Award-winning filmmaker Olivia Wilde paid a visit to her second home aka Tracy Anderson's members-only gym in Studio City on Monday.

The 39-year-old mother-of-two bared her taut midriff in a black sports bra, matching high-waisted leggings, and Adidas sneakers for her invigorating workout.

Olivia hauled a yellow tote, a bottle of Proud Source Rocky Mountain Spring Water, and made sure to scrape her chestnut brown locks into a ponytail.

Wilde - who just sold her four-bedroom Silver Lake home for $4.2M - also sported $193 Ray-Ban 'Wayfarer Reverse' sunglasses over her makeup-free complexion.

The 48-year-old celebrity fitness trainer charges a $1,500 initiation fee plus annual dues for VIP access to her gym - according to Town & Country.

And it's worth every penny for the fit native New Yorker, who sweats so much at Tracy Anderson Method Studio she needs to towel off afterwards.

Last week, Olivia was in New York City for fashion week and she sat down with New York City comedian Kareem Rahma to be his first A-list guest on his web series, Subway Takes, which dropped Wednesday.

During their discussion about karaoke, Wilde (born Cockburn) declared two-time Grammy winner Justin Bieber the 'greatest singer on Earth.'

The 29-year-old Canadian crooner is featured on three-time Grammy winner Diddy's new R&B track Moments, which was released last Thursday.

'Good singers shouldn't do karaoke. It's not for them,' the Ad Lucem producer-star opined.

'They can go get paid to do that. We in the non-good singing community paid to be able to go and sing. We pay good money to be able to go and sing badly. I'm terrible [at karaoke], but that's the point...I don't sing. I don't even sing happy birthday because it'll ruin it. I can't sing so I'm an ideal karaoke partner!'

Olivia added: 'It doesn't even matter how good you are. Like there's no singer good enough that I want to see them do karaoke well.'

At that, the comments section in Subway Takes' Instagram and TikTok accounts lit up with followers claiming Wilde was 'taking shots at' her ex-boyfriend - two-time Grammy winner Harry Styles - who 'loves karaoke.'

The 29-year-old British belter not only appeared on The Late Late Show's Carpool Karaoke segment twice - he sung ABBA in front of Ashton Kutcher, Backstreet Boys' 1998 hit I Want It That Way in front of Taylor Swift, and Wham! 1986 classic Last Christmas with Alexa Chung.

The Conscious Commerce co-founder 'took a break' from dating Harry last November after two years, and he's currently canoodling Independent Spirit Award-winning actress Taylour Paige.

Olivia has two children - son Otis Alexander Sudeikis, 8; and daughter Daisy Josephine Sudeikis, 6 - from her eight-year relationship with ex-fiancé Jason Sudeikis, which ended in November 2020.

Wilde will next strap on an apron and join Jamie Lee Curtis, Daryl Hannah, Sarah Paulson, Kristen Bell, and Chrissy Teigen as celebrity servers at the One Fair Wage benefit in Los Angeles this Thursday.

The non-profit group of restaurant workers and owners is 'a leading organization fighting to increase the minimum wage nationwide with a special focus on the restaurant industry.'

The ongoing WGA/SAG-AFTRA strikes have paused all other projects for the Babylon actress, including a small-screen adaptation of Jennifer Egan's 2010 Pulitzer Prize-winning novel A Visit from the Goon Squad.

Olivia is also attached to direct an upcoming Spider-Woman film for Sony, a Christmas buddy film for Universal, and a biopic on gymnast Kerri Strug for Searchlight Pictures.
