Being someone’s BFF is a big deal – you don’t hand over the other half of your “Best Friends” necklace to just anyone. Having a romantic partner who is also your best friend potentially sounds perfect. With your BFF as your romantic partner, you get the best of both worlds, someone with whom you can laugh, share your life and cuddle. When you look at seemingly happy celebrity couples like Ashton Kutcher and Mila Kunis, or Leslie Mann and Judd Apatow, not only do they appear to be in love, but they also seem to genuinely enjoy hanging out together.
