Amanda Bynes was spotted sporting blue eyebrows and carrying a black Dior handbag in Los Angeles on Monday.
The 40-year-old actress - who celebrated her birthday on April 3 - wore a green T-shirt, grey shorts, and black sneakers.
Her multi-toned hair was partially pulled back, with the former Nickelodeon star rocking platinum blonde roots, a darker blonde middle, and black ends.
She also flaunted long, purple nails while carrying a vape pen.
Bynes was notably holding the designer purse that Princess Diana made famous in the mid 1990s.
Originally called the Chouchou, it was later renamed the Lady after the beloved royal popularized it in 1995.
Bynes released a new song on April 9 after teasing her return to music in January.
She took to Instagram earlier this month to promote the single, called Girlfriend.
The former child star appeared in a video with freshly bleached blonde hair, heavy dark eyebrows, and shimmery makeup.
'What's up, everybody? I just wanted to let you all know that Girlfriend is out now on Spotify and all the streaming platforms,' she said to her 675,000 followers in the clip.
'Please listen. Thank you so much, I really appreciate it. I'm so glad you're all loving it. The response has been super positive so far,' the former child star added.
It came days after she signed to the distribution platform Create Music Group.
Girlfriend was created with help from Zabba and Fenix Flexin, with Bynes receiving writing credits on the song's YouTube link.
The track's cover art is minimalistic - a simple photo of a snowy landscape featuring powder-covered trees and a lavender sky.

Bynes recently released a song called Girlfriend, three months after teasing her return to music.
Create Music Group described the song as a blend of 'melodic rap with EDM-inspired production, creating a catchy, high-replay record with a smooth West Coast bounce' in a statement shared with E! News.
The description continued, 'Built around a strong hook and confident, flirt-heavy energy, it's designed for repeat listens and wide playlist appeal.'
Bynes initially gave fans a snippet of the nearly three-minute song in late January.
Then in February she revealed in an Instagram post, '@fenixflexinofficial is going to be on my song GIRLFRIEND ! straight fire!!!!!!!!!'
The former All That sensation had previously told her followers, 'I wanted to make a quick post just to let you know I'm going back into the studio tomorrow to work on my song girlfriend.'
She added, 'I'm so excited to see how it turns out and I really can't wait for you all to hear it as well.'
