Paris Hilton and new flame Doug Reinhardt, who are still currently enjoying a bit of vacay time in Hawaii, appear to have taken their relationship to the next level. Doug‘s mother Kelly has joined the pair on their holiday and was seen chillin’ with her son and his new ladylove on the island of Maui this week, behold:

It’s hard to know what to wear when you meet a new boyfriend’s parents for the first time. Is the dress too low-cut? The hemline too short? Or, in Paris Hilton’s case, will your new mother-in-law’s outfit overshadow yours? As the heiress and new boyfriend Doug Reinhardt holidayed in Hawaii yesterday, they were joined by his lookalike mother. With their bleached blonde hair, tanned skin, lipgloss and sundresses Paris and Kelly Reinhardt could have been sisters. But while Paris carried a petite white bag she was out-accessorized by Kelly, who chose an eye-catching oversized embellished designer bag.

Oh yes … yes, yes, yes … you can DEFFO tell that Paris fits in PERFECTLY with the Reinhardts. If I remember correctly, and I think I do, the Reinhardt family got their riches because they invented the frozen burrito. As you may recall, Casey Reinhardt (Doug‘s younger sister) was part of the cast of the second season of MTV‘s Laguna Beach: The Real Orange County and explained to her friends that that was her her family made their money … via the invention of the frozen burrito(I remember the scene, cuz Casey was screaming for her maid Esmeralda to make a batch of quesadillas for her and her friends to eat on her bed … and she called them quesa-dillas with the Ls incorrectly pronounced). My point is that a hotel heirass and a frozen burrito heir sound like they were truly made for one another. Paris Hilton need only look at Mama Reinhardt to see her future … I can’t get over how well-suited they are for one another.

But Pug Dilton did more in Hawaii than just hang out with Doug‘s mom … oh yes … they spent part of their time scuba diving and mugging for the cameras, natch! After the jump, check out more pics of the playful pair in paradise …

The two, who are staying at the exclusive Four Seasons resort in Maui, later enjoyed a scuba diving trip. Wetsuit-clad Paris was photographed grinning as she swam underwater. The 28-year-old then gave Reinhardt a kiss for the cameras. Normally always seen with perfect hair and make-up, Paris had opted for a more simple style with her blonde hair tied back with a small quiff. Reinhardt, who stars in MTV reality series The Hills, has previously been linked to his co-star Lauren Conrad and Hairspray actress Amanda Bynes. But it seems the baseball player and reality TV star is smitten with Paris. “She’s the most beautiful girl on the planet,” he said. “She’s amazing both inside and out.” The couple were seen kissing and holding hands throughout a birthday dinner for Paris at the weekend, before kissing on stage in a club.

“The most beautiful girl on the planet”? “Amazing both inside and out”? BWAHAHAHAHAHA! OK. As long as he truly believes that, this pair will prolly stay together forever … which would greatly benefit the world, I know it. Long live, Pug Dilton! I’m not sure what is going on in that 5th pic where Paris was on her knees but … as long as she keeps that biz relegated to Doug‘s nether region, it’s all good. Oh my … I wonder what other adventures are in store for these happy lovebirds.
