Teen Mom OG has chronicled a bunch of momentous life occasions — and during the upcoming two-hour premiere, cameras were present for one of Maci’s biggest moments: her engagement to her beau Taylor.

In the sneak below, we have a preview of Jayde’s papa talking about the impending question, which unfolded on a beautiful beach in Southern California. So how did the Tennessean react to the special ask? There’s a taste of it in the sweet clip — but you will have to wait and see her entire reaction on Monday. (Such a cliffhanger!)

Meanwhile, in honor of Maci and Taylor’s milestone, we're taking a look back at the other proposals starring the young mama’s cohorts. Enjoy the throwback clips below, and be sure to watch Teen Mom OG every Monday at 9/8c!

Catelynn and Tyler

During Season 1, an emotional Ty admitted that he wanted to “grow old” with his sweetheart and presented her with a diamond ring. Now, the duo will soon celebrate their one-year wedding anniversary — the young parents said “I do” in August 2015.

Amber and Gary

Leah’s parents first became betrothed during their installment of 16 & Pregnant, but the young dad asked his longtime companion the important query again during a Season 2 trip to Florida. After a series of makeups and breakups, the pair ultimately parted ways and settled with different partners.

Amber and Matt

The Indiana native kept her relationship with the Bostonian under wraps from production -- but shortly after he made his debut, Matt stated that he'd "really, really like to do something right" and asked a visibly stunned Amber to marry him.
