Steven Tyler and his girlfriend of five years, Erin Brady, spent their Christmas in Maui, where she was spotting rocking some stunning engagement bling.
The large diamond solitaire was hidden from view when the couple passed through the airport, but became visible when they posed for photos with fans.
This will be Tyler's third marriage, as he tied the knot to clothing designer Teresa Barrick, which ended in 2006. His first marriage was to Cyrinda Foxe, an ex-Warhol model, from 1978 to 1987.
