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.
"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.
