Jennylyn Mercado and Dennis Trillo once again win at Halloween with cool Bob Ross and Mona Lisa costume

Jennylyn Mercado and Dennis Trillo set aside their big life news and dressed as beloved painter Bob Ross (Jennylyn) and Mona Lisa (Dennis) for Halloween.

On Instagram, the newly engaged father-to-be posted their cool couple costume, with Jennylyn dressed to look like Bob: curly wig, a pipe, and dressed in the signature baby blue polo.

Dennis, meanwhile, inserted his mug on the famous Mona Lisa painting.

"I really believe that if you practice enough you could paint the 'Mona Lisa' with a two-inch brush,” he wrote in the caption, addressing the painter as Tito Bob Ross.

The couple are constant participants in Halloween, gamely dressing up as a pair. Last year, they came as Joe Exotic and Carole Baskin of "Tiger King." Previously, they dressed up as Walt and Jesse of "Breaking Bad."

Jennylyn and Dennis announced their engagement last week. What more, the two are expecting a baby! So thrilling, right? — LA, GMA News
