Zac Efron Officially Goes Bi, Plus Eight Other Modern Celebrity Couples

Did you hear that? It was the sound of millions of hearts breaking after Zac Efron, otherwise known as the "sexiest mofo alive", and Michele Rodriguez were photographed being very cuddly with one another while on holiday in Sardinia. (Apprently that whole "Italian Daddy" thing Zac had with Gianluca Vacchi was just a phase.) Now, the world waits with bated breath for Efron and Rodriguez's publicists to release a statement. Meanwhile, Zac's former love interest, Vanessa Hudgens, was snapped by paparazzi looking crestfallen in West Hollywood. Poor thing.

Rumors about 35-year-old Rodriguez's sexual orientation have swirled for years. She first admitted to experimenting with both sexes during a 2006 interview with Cosmo, and has since been very open about being bisexual. At 26, Efron is in his sexual prime. We can only imagine the amount of testosterone raging through his veins at any given moment. All those factors combined likely mean lots and lots of hanky panky between the couple, and maybe even some kinky threesomes.

Of course, Zac and Michelle aren't the first celebrity pairing where one of the parties is bisexual. Scroll down for eight more high profile "modern" couples from over the years.

Laurence Olivier and Vivien Leigh

English actor Laurence Olivier married Oscar-winning actress Vivien Leigh in 1940. Not only was Olivier reportedly bisexual in real life, but he also played one in a deleted scene from the original version of the 1960 epic Spartacus. The scene was added back into the film in 1991, finally giving the public an opportunity to hear "Some people like oysters. Some people like snails. I like oysters & snails," which is about as blatant a euphemism for bisexuality as any ever uttered.

Angelina Jolie and Brad Pitt

Angelina Jolie has never been shy about her love of both men and women. In 1997, she told Girlfriends magazine, "I would probably have married Jenny Shimizu if I hadn't married my husband. I fell in love with her the first second I saw her." She again addressed her sexuality in 2003 when Barbara Walters asked if she was bisexual and Jolie answered, "Of course."

Anna Paquin and Stephen Moyer

Anna Paquin said she batted for both teams in a 2010 PSA for Cyndi Lauper's True Colors Fund. That same year, she married her True Blood co-star Stephen Moyer.

James Dean and Ursula Andress

James Dean's sexuality has been a hotly contested topic over the years, with some claiming the actor was gay, others saying he was bisexual, and a few suggesting he was gay "for trade," as a means of advancing his career. We'll probably never know for certain. What we do know is that Dean dated Swiss actress Ursula Andress from 1953-1955, and that he was also romantically linked to Italian actress Pier Angelia and Rogers Brackett, a very well-connected ad exec.

Fergie and Josh Duhamel

Fergie officially came out as bisexual in May 2009 interview with The Sun. She later reconfirmed this during an interview with The Advocate. The pop star met actor Josh Duhamel in 2004. They were married in 2009.

Frieda Kahlo and Diego Rivera

Mexican painter Frieda Kahlo was openly bisexual at a time when speaking about sexuality was considered taboo. She married painter Diego Rivera in 1929, who is said to have "tolerated" her affairs with women, which included a relationship with Josephine Baker.

Johnny Depp and Amber Heard

In 2010, actress Amber Heard came out at a GLAAD event, saying she has had successful relationships with both men and women. In 2012, she and Johnny Depp started dating. The couple announced their engagement in December 2013.

Billie Joe Armstrong and Adrienne Nesser

Green Day frontman Billie Joe Armstrong married Adrienne Nesser in 1994. A year later, he acknowledged swinging both ways in an interview with the Advocate. Earlier this year, he told Rolling Stone that many songs his album Dookie was largely about being bisexual and his struggles with finding his identity.
