AceShowbiz - Singer and actress Hilary Duff has sparked rumours she's planning to get married again after flashing a gold ring in a telling Instagram snap.
The "So Yesterday" singer, who is pregnant with boyfriend Matthew Koma's baby, beamed as she peered over her new bling - a gold diamond starburst ring from Fox & Bond - which she wore on her wedding finger.
"This vintagey looking sparkly number from @foxandbond has me smiling today," the "Younger" star captioned the picture she posted on Wednesday, September 12.
Fans wanting to know more about the ring discovered it's part of the jewellery brand's engagement collection.
It appears Duff's family and friends were just as surprised as fans, with sister Haylie writing: "Ummm, I thought this was something else."
Duff has yet to confirm she's engaged.
She announced she was expecting a second child - a baby girl - earlier this summer after reconnecting with on-off boyfriend Koma last year (17).
She also shares six-year-old son Luca with her ex-husband, Mike Comrie.
