Jennifer Lawrence turned heads and set tongues wagging when she hit the red carpet today for the debut of her newest blockbuster X-Men: Apocalypse in London.

The actress was wearing a sexy Dior Haute Couture silk gown with cut-outs, but everyone is talking about the huge diamond ring she sported on her ‘ring finger’. Why would she wear an engagement ring on THAT finger if she isn’t engaged??

So, we’re left wondering whether the notoriously private star has managed to keep a boyfriend secret and is now a Bride-to-Be!

Jen has previously dated X-Men actor Nicholas Hoult and has been linked to Coldplay frontman Chris Martin, but no word yet on whether Jen is officially off-the-market.
