Donnie Wahlberg, Becca Tilley & Ashley Iaconetti
In between performing at the iHeart80's concert, the New Kids on the Block member got the chance to catch up with The Bachelor fan-favorites.
Russell Crowe & RZA
The actor has worked with the Wu-Tang Clan rapper on several movies, including The Man with the Iron Fists, American Gangster and The Next Three Days. But their bond goes much deeper than that. "As friends, we talk," Crowe tells Fuse. "It is no effort for me to give a friend advice. Film has many gods and you have to understand, as a director, you will be required to please and appease them all."
John Mayer & Bob Saget
They may seem like an odd duo to dine together, but the singer and Full House star did just that at L.A. eatery Craig's after being pals for several years.
Gigi Hadid, Allyson Shapiro
After attending mom's luxury luncheon in New York City, Jill Zarin's daughter meets up with the famous supermodel at 1 OAK.
Justin Bieber & David Hasselhoff
After collaborating on a secret video shoot, the Baywatch alum shared his thoughts on the "Baby" singer. "Justin is a great guy," he told E! News. "He's cool. We're friends."
Michelle Dockery & Pippa Middleton
Before running into each other again at Wimbledon, the unlikely duo first crossed paths at the Downton Abbey set. "She actually came on-set with her brother, James, a few years ago," Dockery told E! News."They are good fans of the show."
David Beckham & Snoop Dogg
When the "footballer" moved to L.A. and became a "soccer player," he befriended the rapper. Becks appeared on Snoop's reality show, the two played soccer and Snoop plays his new music for David first. Weirdness: 8/10
Dakota Fanning & Kristen Stewart
The two former child actors have worked on two films, Twilight and The Runaways, but Dakota says their friendship isn't based on work, "When we're together, we're not talking about movie stuff." Weirdness: 3/10
Nicki Minaj & Anna Wintour
The two have two very different approaches to fashion (has Anna ever been bedazzled?), but they bonded in the front row of an Oscar de la Renta show and Anna scored a name-drop in one of Nicki's raps. Weirdness: 7/10
50 Cent & Bette Midler
Now this is one strange duet! Fiddy met Bette working for the charity New York Restoration Project, where she gushed, "He's one of the newest members of our tribe. He's really made my life worth living." Weirdness: 9/10
Taylor Swift & Lena Dunham
Taylor is a self-proclaimed good girl. Lena isn't affraid to stir the pot. But they have a lot of mutual respect for each other and the Girls creator described T.Swift's show as the "most life-affirming thing I've experienced." Weirdness: 6/10
Lindsay Lohan & Woody Allen
The actress and director met at a party and have been spotted together a few times since. But Woody says there relationship is strickly social, (probably) bonding over bizarre family dynamics and life in the '60s. Weirdness: 8/10
Britney Spears & Paris Hilton
These two landed on the cover of Newsweek with the headline "The Girls Gone Wild Effect," which is something to bond over. Other mutual interests: Partying, going out, clubbing. Their friendship eventually fizzled. Weirdness: 2/10
Robert Pattinson & Vince Vaughn
The Twilight hunk accompanied the funny man for a boys' night out on the town (Joaquin Phoenix was also in attendance), where R.Pattz surely made at least one Wedding Crashers reference. We assume. Weirdness: 5/10
Russell Brand & Helen Mirren
The Brits joined forces for Arthur, and Russell gifted his costar a diamond safety-pin necklace. She gushed over him, "He is the archetypal bad boy, who is really just the best, goodest boy you could possibly meet." Weirdness: 7/10
Jennifer Lopez & Leah Remini
The former King of Queens actress has been supertight with Jenny From the Block for a while now, bonding over fashion and tweeting cutesy things at each other with the hashtag "#luckybesties." Weirdness: 3/10
Gwyneth Paltrow & Jay-Z
The Goop goddess herself is actually friends with both Jay and his wife, Beyoncé, though you might be more surprised to learn that Gwyn is an intense rap enthusiast and her kids even call Mr. Carter "Uncle Jay." Weirdness: 5/10
Reese Witherspoon & Mindy Kaling
We're guessing that the queen of rom-coms and the No. 1 fan of rom-coms probably discuss action films and sci-fi movies when they lunch together, right? Or they just recite When Harry Met Sally line for line. Weirdness: 3/10
Brad Pitt & Jonah Hill
You might not expect the hunky thespian to be close with the dude from Superbad, but look at it this way: Pitt is a total prankster (says Jonah) and Jonah is now a serious Oscar nominee (for their film Moneyball). Weirdness: 6/10
Eminem & Elton John
The controversial rapper joined forces with Sir Elton at the 2001 Grammys and later Em turned to his new friend for support getting sober: "I told him, 'Look, I'm going through a problem and I need your advice.'" Weirdness: 7/10
Mel Gibson & Jodie Foster
The two have worked together (in Maverick and Foster directed him in Beaver) but behind the scenes, the two have become best friends, with Jodie saying Mel "saved" her and Mel claiming, "I kiss the ground she walks on." Weirdness: Infinity
