Shayne Lamas is glowing -- and not just because she's currently expecting her first child with husband Nik Richie.

The 25-year-old Bachelor winner and E! reality star spent the weekend in Cabo San Lucas, Mexico, where the mother-to-be worked on her tan while lounging poolside at the Casa Dorada Resort.

Lamas is eager to become a mother -- and to resume her Hollywood lifestyle.

"I can't wait to dance on tables again," she tweeted September 3. "I am only 25! The things you miss while pregnant -- that's one of mine."

On April 19, Lamas eloped with Richie, whom she had met just hours earlier, at the Little White Wedding Chapel in Las Vegas. They settled on the $519 "Michael Jordan Package" at the chapel, which included 36 professional photos and a DVD copy of the wedding.

Coincidentally, Little White Wedding Chapel is the same venue where Britney Spears famously got hitched to childhood boyfriend Jason Alexander in 2004; their union was annulled within days.
