Demi Moore reportedly partied with Miley Cyrus just nine days before she was hospitalised.

The 'Striptease' star – who was taken to hospital last week after she suffered a seizure - is said to have attended a birthday bash put on for her 'LOL' co-star's boyfriend Liam Hemsworth at Club Icon in Los Angeles last month.

Sources told TMZ.com that Demi attended the party - which saw the 'Hunger Games' actor presented with a penis-shaped cake to celebrate reaching his 22nd year - with her 23-year-old daughter Rumer and her friends.

The 49-year-old actress - who split from husband Ashton Kutcher in November amid speculation he had cheated on her – was spotted sipping Red Bull in the VIP section of the club for most of the night before she and Rumer left sometime after midnight.

Following her release from hospital, Demi has been visited by her ex-husband Bruce Willis – who have daughters Rumer and Tallulah, 18, who are now living with him and Scout, 20, together – and Ashton, who went to see her on Monday (30.01.12).

Bruce is thought to have urged Demi to seek help before she was hospitalised last week after she was rumoured to be suffering from substance abuse and anorexia.

A source told People magazine: "He was worried about her and wanted her to get better. Many of her friends did the same thing, but she just wouldn't listen."
