The 'Real Love' hitmaker insists she isn't ''psychotic'' but if she had the chance to be invisible, she would use her new-found super-power to spend a day with her idol.
She said: ''If I was invisible for a day, I'd probably follow Beyonce around as she's my hero.
''I wouldn't break into her house or anything - I'm not psychotic.''
As well as Beyonce, Jess was also a big admirer of late singer Amy Winehouse and sleeps beneath a picture of the 'Rehab' star.
She said: ''Recently, I was given a big picture of Amy Winehouse in a cool frame from my parents.
''She's very inspirational to me, so I've hung it above my bed.''
Though Jess has just released her debut album 'I Cry When I Laugh', she admits she found it hard to sign off on the finished record because she is such a perfectionist.
She told heat magazine: ''I'm a perfectionist, so if something isn't how I want it to be, or it doesn't feel right, I beat myself up over it.
''It was hard letting go of my album and accepting it was finished.''
'Smalls Change (Meditations Upon Ageing)' arrives in April.
The two awards have made for a great 72nd birthday present for the country music icon.
