Holt enjoyed three magnificent years at Norwich under Lambert, winning the club's player of the year on each occasion.
He also earned a place in the Canaries hall of fame in 2012 for his exploits in East Anglia.
Holt helped Norwich to successive promotions from League One to the Premier League.
He scored 21 goals as they went up from the Championship and he was a pivotal figure in that first campaign in the top-flight, bagging 15 goals.
In total he scored 23 goals in 70 Premier League games in yellow and green.
The 32-year-old forward joined the Latics in the summer for around £2m from Norwich but only scored twice as injuries hampered his progress.
His move to the Midlands was an ideal opportunity to work again with the boss he said he'd have followed anywhere.
Lambert expects good things from Holt and says the "old-fashioned No.9" will "surprise a few."
Alongside current Villa forwards Christian Benteke, Gabriel Agbonlahor and Andreas Weimann - and in the absence of Libor Kozak who broke his leg just after Christmas - Lambert says he is pleased to have secured the services of an experienced frontman.
"When I knew Grant had become available it was something I wanted to pursue quickly because he'll add strength and experience. Having worked with him for three years at Norwich, I know what he can do," said Lambert.
"Coming back into the Premier League will rekindle that desire in him to succeed again at this level."
Holt is keen to find his best form again under Lambert.
"It's a massive opportunity for me personally, an opportunity I couldn't turn down," he said.
"To be able to come back into the Premier League, especially at a club as big as Villa, is fantastic."
