LONDON: It has been reported recently that Selena Gomez’s mysterious decision to scrap the Australian leg of her world tour was down to a secret battle with Lupus, but the star seems to be much cheerier now, if her Twitter feed is anything to go by.

The ‘Come And Get It’ hitmaker, who hit the top spot on the Billboard album chart last summer with her latest album Stars Dance, told her followers that she was “finally home” after a trip away, and even stopped by Britney Spears’ gig in Las Vegas alongside Sia, Katy Perry and Miley Cyrus.

“Finally home,” she wrote alongside an Instagram photo, looking chilled and casual in sunglasses and a comfy jacket in the back of a car.

She later gushed after the Britney Piece Of Me show: “Sia!! Thank you soooo much for taking me to Britney!!!! Ahhhh.”

Speaking about the lupus rumors, a source had previously told HollywoodLife: “Selena will not be happy that this is out there. She really wanted to keep this to herself because she doesn’t want it to affect people’s opinions of her and what she’s capable of.

“This is her own personal business and she wants to keep it that way.”

The star has yet to officially comment on the speculation.
