Chris Hemsworth's pregnant wife Elsa Pataky has been admitted to hospital in Los Angeles.

The Spanish actress, who is expecting twins, was spotted with the Australian actor at Cedars Sinai Medical Center in West Hollywood on Thursday (20.03.14), sparking reports she was in labour.

An insider told gossip website TMZ.com that two security guards accompanied the couple, who already have a 22-month-old daughter India Rose, to the hospital and watched over their private suite.

The 'Thor' star was also seen strolling around the hallway, escorted by another guard.

Proud father Chris, 30, previously gushed about family life and admitted he is happiest when he is with his wife and daughter.

He said: ''Being a father is certainly a task. But the best one that I could ever ask for. Being home, being with the family, that's what it's about ... It makes me much more relaxed with work, because I have something that is far more important to me now.''

The actor married Elsa, 37, in 2010 after a whirlwind romance.

The blonde beauty went grocery shopping with some family members in Malibu on Monday (17.03.14), before stopping to pick up a healthy green juice.
