AFL superstar Lance Franklin re-emerged into the public eye on Thursday night after more than a month out of the spotlight due to mental health issues.

Franklin took to Twitter to give brother-in-law and Wallabies star Matt Giteau a gentle ribbing ahead of his 100th Test after the official Wallabies Twitter account tweeted a video of a fresh-faced Giteau meeting Queen Elizabeth at Buckingham Palace back in 2002.

"Looking older there @giteau_rugby ," Franklin quipped.

The Wallabies are next in action on Monday morning against Scotland in their Rugby World Cup quarter-final at Twickenham.
