Macaulay Culkin's estranged father reportedly suffered a massive stroke on Tuesday (21.01.14).

The 'Home Alone' star, 33, and his family including his five siblings, Shane, Kieran, Quinn, Christian and Rory, have been summoned to a hospital in Oregon as their father, Kit Culkin, is in very bad shape.

A source told gossip website that the 69 year old, who managed Macaulay's career until the family got into a dispute over money when he was 14, has lost almost all of his motor functions and the prognosis is not good.

Emergency services were called to Kit's home in Grants Pass, Oregon just after 1pm on Tuesday.

Macaulay was not available for comment.

The actor is currently dating actress Jordan Lane Price - who bears a striking resemblance to his ex-girlfriend Mila Kunis - and friends recently said she has been a fantastic positive influence on the former child star, who was rumoured to be battling a drug problem last year.

A source previously said: ''For the first time in years Macaulay looks happy and healthy. Jordan has rescued him from his drug hell, and its ironic that she's a double for Mila, who dumped him because of his drug use.''
