Adam Lambert's latest appearance in Glee has aired in the US.

The singer is guest starring on the fifth season of the popular TV show and last night (November 28) he made his second cameo.

The 'Trespassing' man appeared alongside a puppet version of himself in the episode Puppet Master as the show took a somewhat odd turn.

Lambert also lent vocals to a cover of Madonna's iconic track 'Into The Groove'.

His first appearance on Glee meanwhile came in the shape of the recent episode A Katy or a Gaga.

The 'Better Than I Know Myself' man had a go at the likes of Lady Gaga's 'Marry The Night' as he debuted his Elliot Gilbert character.

His cameo in the episode earned rave reviews and delighted fans.
