It's like prom night all over again!
Paris Hilton and River Viiperi combined the best of both worlds — prom season and Cannes — at amfAR's 20th Annual Cinema Against AIDS Gala on Thursday.
Lil' Wayne's label mate went all out in a sheer feathered pink frock that every single showgirl in Vegas would covet, while the gorgeous sculpture of a man that is River kept it classy in a simple tux.
Wonder if they were able to engage in some PDA at the event?
It just wouldn't be right if they didn't broadcast their love all over the place!

After a harrowing night that included pushing and lots of yelling, River Viiperi and Paris Hilton enjoyed a drama-free evening in Cannes on Wednesday.
The two lovebirds joined the star-studded crowd aboard Roberto Cavalli's yacht where they once again packed on the PDA — and looked good doing it!
The newest addition to Cash Money Records wore a shimmery beaded dress with blue feathers along the hem while her hunk of man meat looked handsome in a blue suit and black shirt.
We think it's safe to say these two definitely had Cavalli's boat rockin' last night. They couldn't keep their hands off each other!

True love has no shame!
Paris Hilton and River Viiperi are in LUUUURVE and they don't care who knows it! In fact, they want EVERYBODY to know!
The two were ALL OVER each other at the Gotha Club in Cannes on Thursday with Paris straddling and smooching River like an Army wife who hasn't seen her man in a year.
But, who are we kidding, we'd be doing the same if River was OUR man! Ha!
After the makeout sesh, the 32-year-old heiress casually reapplied her pink lipgloss, as you do.
And don't they look so patriotic in that red Herve Leger bandage dress and cool blue suit?
Don't ever break up, you crazy kids!

Paris Hilton has been making the talk show rounds and she was dressed to impress for her appearance on the Late Show with David Letterman on Thursday.
She and her hunkalicious boyfriend River Viiperi posed for paps just before walking into the New York studios looking like a couple of Manhattan hotties.
Paris wore a black Herve Leger by Max Azria cutout bandage dress along with Louboutin heels and matching purse.
River, meanwhile, was just her handsome arm candy in his usual black jacket and shades.
Honestly, who needs accessories when you have a beautiful boyfriend!

It's like they're attached at the hip!
The impossibly hot River Viiperi accompanied girlfriend Paris Hilton to the Wendy Williams Show in NYC on Thursday.
Paris put on a flirty white A-line frock with shoulder cut-outs to talk up her latest fragrance Dazzle with Wendy, while River wore way too many items of clothing while kicking back in the audience.
When is he going to do another photo shoot or runway show?
We want him SHIRTLESS and we want it NOW!

Oh, look, it's Barbie and Ken!
Actually, it's Paris Hilton and River Viiperi, but that's kind of the same thing, right?
The lovebirds jetted on over to Las Vegas on Saturday to make their presence known at the grand opening of Hakkasan nightclub in the MGM Grand.
Paris was a shoo-in for nightclub Barbie in a gold sequined Jovani dress and nude Louboutin pumps, while her real-life Ken doll sported his go-to outfit of jeans, plain white tee, leather jacket, and that "Paris" snapback cap he loves so much.
Hey, don't hate them because they're beautiful! LOLz!

Such attractive lovebirds!
Paris Hilton and her deeee-licious boyfriend River Viiperi were spotted leaving Mr. Chow's after what we can only assume was a romantical date night for the two.
Paris wore a striped shirt that displayed her name across it along with black skinnies while River looked extra fit in his jeans, leather jacket and black snapback.
Super cute couple, right??
