It's time for a Haus of Gaga headcount.

In the decade that we've known Lady Gaga, it's seemed as though the woman otherwise known as Stefani Joanne Angelina Germanotta arrived on the scene fully-formed, a product of otherworldly talent, fierce fashion scene, and unflappable determination. But as we all know, behind every one of us is a collection of supporters, influencers and loved ones all helping to shape us into the people we are and will still become. And that's no different for Mother Monster.

And the latest name to be inducted into the Haus? Jeremy Renner coming in truly from out of left field.

Just days before the "Shallow" singer headed south of the border to ring in her 33rd birthday on Thursday, March 28 in what a source tells E! News is her "happy place"—Cabo San Lucas—Gaga and the Avengers star made headlines when it got out that they've apparently been spending time together. While some were quick to assume the relationship was romantic in nature, an insider tells us the pair have been friends for "a while" and "often hang out when they both are in town."

Renner's just the latest in a long line of names—some famous, some not—to reveal themselves to be of importance to the Oscar-winning diva. So, in honor of her big day, let's take a look at all the people who've made an impact on Mother Monster over the years, helping to shape her into the icon we know and love today.
