Taking a dig at actor George Clooney's Italian wedding, actor Neil Patrick Harris has dared the Hollywood heartthrob to share his wedding pictures on a talk show.

Harris, who got married to David Burtka in Italy last month, challenged Clooney while sharing his wedding photographs on TV show "Late Night With David Letterman" Sep 29, reports dailymail.co.uk.

"Take that Clooney! I don't see you showing pictures of your wedding on talk shows!," said the actor.

Clooney exchanged vows with British human rights lawyer Amal Alamuddin in Italy Sep 27. And the couple has shared exclusive photos of the wedding with PEOPLE magazine, in conjunction with Hello! magazine internationally.
