Singer Thelma Plum and former Australian Idol star Tom Jay Williams enjoy sweet treats at Sydney’s Donut King party

Thelma Plum was the icing on the cake, or you could say, the frosting on the donut at an exclusive event hosted by Donut King.

The 28-year-old singer sent fans in a sweet frenzy with an intimate performance as tempting as the sweet treats served at Sydney’s Alexandria.

Ever the style maven, Thelma sizzled in an animal print dress offset by colorful floral accents.

Her outfit was a striking ensemble, matched only by her breath-taking voice that thrilled the audience.

None other than former Australian Idol star Tom Jay Williams, who recently returned to the spotlight, added his rock and roll flair to the guest list.
