Heather Locklear's psychiatric hold has been extended.

The Melrose Place star's stay in a Los Angeles facility 'was originally only supposed to last for 3 days' but is not set to be extended 'an additional 2 weeks' according to TMZ.

Last week, DailyMail.Com reported that on Monday the 57-year-old had a fight with her boyfriend Chris Heisser, which resulted in her being placed on a 5150 hold.

Troubled: Heather Locklear's psychiatric hold has been extended. She's seen here in 2016

The reason for the extension is so that the Spin City actress could undergo 'further evaluation', according to the gossip site's sources.

Members of Heather's inner circle have been speaking about their concerns for the Hot In Cleveland actress, calling her 'unstable', according to People Magazine.

'Heather needs help. Everyone wants her to get better,' one source said.

They added: 'She is unstable and she's had a lot of issues, drug use, and alcohol over the years. No one wants to see her go through something like this.'

The former nineties icon had been getting professional help for months following a string of breakdowns and arrests.

'Heather had been in rehab for three months and got out in early October, the day before her daughter's 21st birthday,' a family friend told People.

They added: 'And for the last month, she has been living privately and low-key.'

That all came to a head on Sunday when a fight erupted between the blonde bombshell and her current boyfriend.

A source told DailyMail that Heather allegedly beat up her Heisser and threw him out of her home. The next day she was placed on the 5150.

The television star shares her 21-year-old daughter Ava with ex Richie Sambora.

'It's very hard on the family,' a source told People. 'Richie is a rock for Ava. She is holding up but always worried about her mother.'
