Ariana Grande and Pete Davidson are Instagram official. The two indulged in some adorable Harry Potter cosplay to mark their new status.

Opening The Chamber Of Secrets

News broke last week that the pop singer and Saturday Night Live star were romantically involved. Their cute Instagram posts make it properly official, though.

The happy new couple took to the social media site Wednesday to share photos of them nerding it up, Harry Potter-style.

Davidson shared a photo of him and Grande wearing matching robes. Davidson wore a Gryffindor sweater while Grande rocked a Slytherin one.

"The chamber of secrets has been opened..." he hilariously captioned the post.

Grande then commented below it, making a pun-based joke about Davidson's intentions with her.

The "No Tears Left To Cry" singer also shared a pic of her Slytherin sweater on Tuesday.

Enjoying Their Time Together

The happy new couple was spotted enjoying a show at The Comedy Store in L.A. on Tuesday evening. Grande was there for moral support, with Davidson performing a standup show.

According to an eyewitness, the two arrived and left together and were very open about their relationship while at the venue.

"Before he went on stage they shared a kiss. It was cute," claimed the insider.

Another source claimed Grande is super happy with Davidson, especially given everything she went through with ex Mac Miller.

"People don't realize what a great sense of humor she has. It makes them a good match. They're having a good time," the insider revealed.

Davidson has struggled in the past with borderline personality disorder, publicly revealing his issues last year, but a source confirmed he's in a good place at the moment.

They're A Good Match

Las week, Grande and Davidson's relationship became public but was said to be just casual at the time. They've been openly flirting on social media ever since, but this is their first photo together.

The pop star confirmed her split from Miller earlier this month after dating for two years. David recently broke things off with girlfriend Cazzie David, also after two years together.

Grande is a long-time Harry Potter fan having shared on numerous occasions how hooked she is on the series. The singer has even met several members of the film adaptations' cast and even named her dog Sirius Black.

According to certain reports, Grande and Davidson were spotted in their matching robes at Universal Studios Hollywood in California last weekend.
