Joel Madden and Nicole Richie have reportedly hit a rough patch in their marriage, but based on their Instagram posts, it seems like all is well!

Last night Joel posted the above shot and captioned it, "Happy Mothers Day to my best friend and partner in rhyme. Best wife, mother and friend a father and his kids could ever ask for ❤️❤️❤️." The day before that, Joel uploaded a shot of Nicole wearing socks with their faces on them and he wrote, "Sock game strong."

While the social media posts are pretty sweet, we have to wonder why Nic was spotted without her wedding ring the other day. The pint-sized starlet was grocery shopping with sister-in-law Cameron Diaz and her left hand was completely naked. And not only that, but there were already a number of reports that the two were "on the brink of divorce."

According to a source for In Touch Weekly, the couple are "spending more time apart because all they do is fight when they’re together ... The last thing she wants is a public split with the children involved, but she’s desperately unhappy." Yikes! The mag also claims that Nicole has sought out the advice of a divorce attorney.

Nicole and Joel have been married since 2010 and they have a daughter Harlow, 7, and son Sparrow, 5. Think they'll stay together or split? Or are these rumors just total baloney?
