18. Cameron Diaz & Benji Madden

Cameron Diaz has dated a number of guys over the years. She reportedly was in a relationship with Jared Leto and Justin Timberlake. Thankfully, she found a man who is brave enough to tie the knot with her: Benji Madden. We all know Diaz from her box office hit films like Charlie’s Angels, Bad Teacher, and our personal favorite, The Other Woman. Madden, on the other hand, is known for being the backing vocalist and lead guitarist of the rock band Good Charlotte. Also, from 2015 to 2016, he served as a coach on The Voice Australia.

The two met because of Madden’s sister-in-law Nicole Richie, who happens to be a close friend of Diaz. Eventually, they privately got married in 2015 at the actress’ Beverly Hills mansion. After years of trying, the couple was blessed with an adorable daughter in December 2019. Keeping their relationship lowkey seems to have worked out for them as they have no plans to contact their lawyers anytime soon.
