So Selena Gomez thinks there's an app to find GHOSTS...she must be on something very high. Right?

It is the sort of admission that is likely to draw ridicule from one's peers.

But that did not stop Selena Gomez admitting she believes spooks really exist to Jimmy Fallon on the Tonight Show on Wednesday.

She even confessed she uses her mobile phone to search for phantoms from beyond the grave everywhere she goes.

‘I believe in ghosts, so I have a ghost app,’ said the 23-year-old pop star, who recently underwent chemotherapy treatment to treat the lupus disease. 

‘I believe that spirits can tap into technology, why not right?’ She asked the incredulous host of The Tonight Show Starring Jimmy Fallon.

Whipping out her phone the former Disney starlet then ran the bizarre app to test the NBC studios for ghouls.

‘This is going to scare me,’ giggled Fallon as the app ran some strange wave formations and inexplicable numbers across her cellphone’s screen. 

After a few seconds it spoke, saying the word ’children’ in a gruff, sinister tone.

‘Children…I don’t have any children so they must be mad at ya’ll,’ said the Texas-born actress and singer.

As Fallon made fun of the app Gomez insisted that it had once picked up people she knew ‘by name’.

Gomez later flashed some leg on the piano to perform her sultry new track Same Old Love, from the album Revival.
