Jennifer Lopez is doing her best: she's taking her rare Birkin bag to the gym, so where else is she?

On Thursday afternoon, Multi-Hifenate was filmed in Los Angeles heading to the gym during what appears to be a rehearsal before the upcoming tour for her ninth and last studio album, which is me.Now

The "Can't Get Enough" singer was spotted showing off her toned abs in Joah Brown's classic sweatsuit, which consisted of a cropped long-sleeved crew neck top and a baggy low-rise jogger.

She paired the comfortable look with ankle-beating Ugg boots and opted for the chestnut colorway that is a hallmark of the brand. She also wore an oversized black aviator shade that covered most of her face. 

However, Lopez's casual attire is by no means casual. Musicians have added an element of surprise - a matte cream croco-embossed Hermes Birkin Beton 45 bag instead of a sporty duffel using silver hardware, an unusual discovery. A similar style is currently on sale in upwards84,500+.

J.Lo has a long history of boosting her athletic wear with a big luxury spin. As someone who wears three fur coats a day and carries two designer bags at once, it is expected at this point that a-Lister will bring her Hermes treasures everywhere with her, including gym, travel and even daytime dates.

Earlier this week, she was spotted in Los Angeles with her lover, Ben Affleck. She opted for a loose denim overalls from the r13 and layered a white long-sleeved top and a scruffy cream cardigan. Lopez once again chose the cozy platform Ugg boots and added a pop color with a bright orange clock Hermes Birkin bag.

This is me...Now: The love story star toted another exclusive style while also celebrating her twins— Max and Emme— in Sweet 16 Japan. Lopez posted a mirror selfie to Instagram on May 2 and had a large earl grey puffer coat and, as you might expect, a huge Himalayan Birkin bag. 

J.Lo's North American tour officially started on the 26th, marking the singer's first circuit. Also do not be surprised if she is already planning to pull out her Birkin on stage.
