Jessie J is heading to the hometown of her co-worker Tom Jones to see where the legend began.
The 'I Gotta Feeling' interpreter has been announced as the Friday night headliner of the Ponty's Big Weekend festival in Pontypridd.
JJ will join Olly Murs, Cover Drive and Alfie Boe in the Rhondda Valley from July 20 — 22.
Weekends don't get much bigger than that.
