You might catch Lady Gaga outside your local pawn shop or antiques dealer after she became addicted to The Antiques Roadshow!
The obsession with all things old started when she was presented with the DVD box-set of the TV show whilst on tour.
Her growing collection of memorabilia includes Dorothy's ruby slippers from The Wizard Of Oz - a gift from her record label worth over $25,000!
A source told The Sun "Lady GaGa is really into her antiques so British pals thought she might be interested in the programme."
"It went down a storm and GaGa hasn't stopped watching the DVDs. She loves how the old people think their antique is a bit of tat but ends up costing thousands. It's right up her street.
