Chris Hemsworth and his wife Elsa Pataky were joined by celebrity friends including Matt Damon at a baby shower celebrating the impending arrival of their twins.

The Thor actor and his Spanish actress wife are already parents to 21-month-old daughter India and are expecting twins in the spring.

Monuments Men star Matt was spotted attending the shower in Los Angeles with his wife Luciana Barrosa and their four daughters, reported the Daily Mail.

The actor was dressed casually in shorts and flip-flops as he arrived at the party with his brood.

Chris, 30, and Elsa, 37, announced the pregnancy in November and last month it was confirmed they are expecting twins.
