Amanda Bynes smiled and waved to the cameras when she showed up at Craig's restaurant in West Hollywood, California on Monday night.
The former What I Like About You star entered the celebrity hotspot wearing a cleavage-baring, zip-up white dress and big sunglasses. An eyewitness tells ET that Kris Jenner was also at the eatery and that both stars were seated in the front room of the establishment.
The appearance marks the first time Bynes has been seen since August.
The 29-year-old actress was last spotted at the SOAR Los Angeles Gala, and tweeted out a picture alongside designer Michael Costello. "Me and the fabulous Michael Costello," she wrote. "(I'm wearing one of his beautiful gowns) at the SOAR Los Angeles Gala!"
She has not tweeted to her official account, which has over 3.5 million followers, since posting the twitpic on Aug. 19.

Bynes also supported Costello in July when she showed up to his and Style PR's capsule collection launch, held in Los Angeles. A blonde Bynes was dressed in another figure-hugging, white dress that she paired with black stilettos and large sunglasses. This was the actress' first public event since her meltdown in 2014, and was also her first public appearance since the 2011 MTV Movie Awards.
In October 2014, the former Nickelodeon child star was placed in a Pasadena treatment center where she was admitted involuntarily.
A week after being released, Bynes said via Twitter that she had been diagnosed as bi-polar and manic depressive. "I'm on medication and I'm seeing my psychologist and psychiatrist weekly so I'm fine," she explained.
ET has seen Bynes grow up and was with her on the set of The Amanda Show in 2001, when she was just 13 years old. Check out the flashback interview:
