Surprise! Liam Hemsworth is engaged (again)! On Instagram Thursday, the 35-year-old actor's longtime girlfriend - now fiancée - shared the exciting news. Gabriella Brooks took to her feed to share a sweet post which featured a black and white snap of her and her man, and yes, there's a ring on THAT finger. The second slide featured a pic of the beach (possibly where he proposed?), while the third showed a close-up of her ring.
