Amanda Seyfried got quite the birthday present at the Porter House last night, following a special screening of "Les Miserables," hosted by Universal Pictures, Working Title Films and Cameron Mackintosh. After taking to a mic in the center of the packed dining room and demanding that Seyfried make herself known to the crowd, her co-star Hugh Jackman teased, "I once gave Barbara Walters a lap dance and I promised her I would never do it again, but seeing as she is not here tonight..." -- and then proceeded to get down.

Indiewire was on the scene to see Jackman strut his stuff. Unfortunately, we were so gobsmacked by the Aussie's crowdpleasing shenanigans that we only hit the record button as he left Seyfried's lap to croon Happy Birthday to the now 27-year-old actress. Watch it below:
