So remember how Jersey Shore alum Ronnie Ortiz-Magro and girlfriend Jen Harley are expecting their first child?

Well, congratulations are in order.

On Tuesday, April 3, the couple welcomed the birth of their first child.

E! was the first to report that Ronnie Ortiz-Magro is now a father.

A source told them that Ronnie is "over the moon" over the birth of his baby girl.

This is wonderful news and marks the beginning of the next chapter of Ronnie and Jen's lives.

The two of them haven't yet made an official announcement, but it seems inevitable.

And it's not like they've been especially subtle about the news. ...

First of all, you know how Jersey Shore: Family Vacation is premiering on Thursday?

Ronnie "mysteriously" skipped the premiere event.

Fans who ere mystified by his absence didn't have long to wonder about what could possibly 

On Monday night, Jen shared some messages with her fans and followers via Instagram stories.

"Ron lands at seven so we have five hours," she shared, while supported by her close friends.

"I'm feeling very very uncomfortable."

It's so sweet that she was so worried about Ronnie getting to be there for the childbirth.

And it's precious, but no surprise, that Ronnie dropped everything -- including professional commitments -- to race home to welcome his baby girl into the world.

In addition to these not-so-subtle clues and E!'s announcement, MTV has confirmed to Us Weekly that the couple's baby was born on Tuesday.

There's no telling when photos will be forthcoming, but for now, we hope that they're all bonding and resting.

Especially Jen. She's the one who did the most work, obviously.

Ronnie recently finished filming Jersey Shore: Family Vacation, a surprising but exciting revival of the classic reality series.

In fact, Jen even appears alongside him in part of the Jersey Shore: Family Vacation teaser trailer.

He joins other past and present costars like Snooki, Pauly D, and JWoww in becoming a parent.

In fact, he's even turned to each of them for advice, and shared that he's really benefiting from that, because they each had different experiences.

Of course, Farley warned him, reminding him that he had broken the hearts of many young woman during his wild youth.

She says that it's appropriate and fitting that he'll raise a daughter while worrying about which men might break her heart.

Since the cast was begging MTV to bring back Jersey Shore, ultimately leading to this revival, it's pretty important to them.

(Admittedly, for most of them, it's probably the money that matters. But that's okay -- filming a reality series is work, and almost no one works for free)

But it's clear that Ronnie has his priorities in the right place, because he raced back to be with his wife while she gave birth to their child.

Seriously, congratulations to Jen Harley and to Ronnie Ortiz-Magro on the birth of their daughter.
