It sort of looks like it.
After all, the Hollywood power couple has been together since 2011 and they have a daughter together. But if they're engaged, they did it secretly.
And that's exactly what a lot of fans seem to think happened.
Forty-one-year-old Mendes has been wearing a ring — a giant emerald, which isn't what most people think of when they picture a traditional engagement ring. But she's been wearing it for some time — and she's been wearing it on the same finger (though not her ring finger, hmm), so it's definitely causing speculation.
E! News reports it was inspired to investigate after seeing Mendes sporting the rock in a recent Instagram photo. Some digging through the actress' social media revealed she started wearing the piece sometime in June, the site reports. It also says she rocked it during a red carpet appearance at an Estée Lauder event last month.
Then again, what if the ring signifies something else? The couple's daughter, who was born in the fall of 2014, is named Esmeralda. An emerald for Esmeralda? It's possible.
E! News reports that a rep for Mendes declined to comment on the actress' personal life, leaving fans to keep speculating based only on the evidence above.
