X17 XCLUSIVE - Paris And Doug's Anguillian Adventure Comes To An End

We've figured out where Paris Hilton and Doug Reinhardt's "secret island" vacay was! The lovebirds are now in Miami, but not before spending a week relaxing at a lux private oceanfront mansion in Anguilla.

The lovebirds flew to the island on Doug's parents' private jet, and they stayed in this massive 12,000 square foot, 8 bedroom estate right on the water. The pad boasts a private swimming pool, tennis court, fitness center, cinema and bars on multiple levels, so it's pretty safe to say Paris and her man were very pampered during their trip.

The couple went scuba diving through ship wrecks and sunned themselves during the day, and at night they dined with Doug's family, which it seems like the heiress may become a part of very soon!

A source tells X17online exclusively:

"Paris and Doug looked like they were on a honeymoon. They would be on the beach for hours, just staring into each other's eyes, kissing and laughing. At dinner Doug's mom was overheard referring to Paris as her "daughter-in-law," and it's pretty clear that Paris' family feels the same way about Doug."

Aww, glad she's finally found her prince charming!
