Honkin' On Robo: Steven Tyler confirmed to have jammed with Zeppelin

Is Jimmy Page trying to make Robert Plant jealous?

Aerosmith's unsung guitar hero

Brad Whitford

has confirmed the rumour that 'Smith singer Steven Tyler took part in a recent jam session with Led Zeppelin members

Jimmy Page, John Paul Jones and Jason Bonham

.

"First of all, they did it for fun,"

Whitford said during an appearance on the syndicated show Todd n Tyler Radio Empire.

Whitford went on to speculate that Page and the boys may be trying to send a message to Robert Plant - who has been reluctant to join a reunited Led Zeppelin again following last year's insanely popular 02 Arena show.

"I actually think Jimmy wanted Steven to come over and play a little bit because, I think, he was trying to light a fire under Robert,"

Whitford said.

"Come on! Come on, Robert, let's go!"
