Silicon Valleyactress Alice Wetterlund has accused her former co-star T.J. Miller of being "a bully and petulant brat" on the set of the show in a series of tweets posted on Wednesday night.

Wetterlund, who appeared in the HBO series for two seasons in 2015-2016, also accused other male cast members of enabling his behaviour.

The "fake bomb threat" refers to an incident that occurred earlier this year, in which Miller was arrested after claiming a female train passenger had "a bomb in her bag".

Wetterlund then followed up on her original tweet with a claim about Miller's behaviour on Silicon Valley.

"While this is the first time we have heard Alice Wetterlund comment on her experiences on Silicon Valley, we are disappointed to learn of her concerns," a HBO spokesperson told The Hollywood Reporter. "HBO and the producers have always taken very seriously our responsibility to create a welcoming and congenial environment for everyone who works on the show."

Last December, Miller was accused of sexually assaulting a woman when he was a student at George Washington University. He released a lengthy statement on Instagram denying the claims.

Mashable has reached out to T.J. Miller's representatives for comment.
