Can't wait for next Monday's Bachelor finale?

The new Us Weekly, out Wednesday, has exclusive details -- and photos -- of Brad Womack's final, pre-proposal moments in South Africa with his last two women standing, Emily Maynard and Chantal O'Brien.

His last date (on Nov. 17) with sweet single mom Maynard, 24? A windy wilderness picnic in Cape Point that began with a helicopter ride. "They ended it with a kiss," an insider tells Us.

As for fiery divorcee O'Brien, 28, she and Womack, 38, opted for something more adventurous the next day, Nov. 18: A whale and shark watch aboard a boat by the Danger Point peninsula. "They held hands," the source observed.

When the time came for the native Texan to give out his final rose and propose -- and give one of the ladies some bad news -- Womack was uncharacteristically nervous, a source says.

Still, "he knew he made the right decision," the insider adds.
