The 25-year-old singer ' who is well known for her eccentric tastes ' is obsessed with the British TV show where people bring in their valuables to find out their value, and friends have now bought her a DVD box set of classic episodes so she can watch them on the road.
A source told The Sun newspaper: "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 old tat but ends up costing thousands. It's right up her street."
The 'Judas' hitmaker herself has some expensive items in her closet ' she was given the red shoes worn by Judy Garland in 1939 movie 'The Wizard of Oz' as a present from her management earlier this year.
It is not the first time Lady Gaga has been linked to a love of television ' she has previously confessed she adores watching cookery shows when she has some down time.
She said: "When I get time off, I like to watch cooking shows, I'm really obsessed with them. I'm a really good cook now, just from watching those shows. My specialty is Italian."
