"Teen Mom OG" star Amber Portwood admits she fell head over heels in love with Matt Baier.

Their whirlwind romance caught many fans by surprise. Many people speculated that the relationship would not last, but when Baier proposed marriage to Portwood while they ate at a diner, it was clear his intentions were to make the mother and reality TV star his wife.

Leah's mom dished to MTV News about the upcoming wedding day, though no date has been set.

"I know for sure my cousin Krystal would be the maid of honor at the wedding," the Indiana native told MTV News. "She's the closest person to me. She's like my best friend."

The future bride did not disclose details about a venue or her highly anticipated wedding gown. She did say that she would like Maci Bookout, Catelynn Lowell and Farrah Abraham to play a role at her ceremony and attend the reception. To learn more about how the 25-year-old would like her co-stars to be involved, watch the video below. 

Meanwhile, "Teen Mom OG's" Farrah Abraham recently returned from her 24th birthday vacation to Cabo San Lucas, Mexico with boyfriend Simon Saran. The former porn star caused quite the stir when she posted a Facebook picture from her vacation in which she's holding a lion cub, reports RadarOnline.

"My Lion Cub doesn't let anyone mess with me WatchOut," Abraham captioned the Facebook photo.

What Abraham may not realize is that many foreign countries -- like Mexico and Thailand -- drug wild animals so that tourists can pet them and take pictures without risk.

People for the Ethical Treatment of Animals reacted to the star's picture post with a quick lesson in the poor conditions animals suffer in drive-by zoos.

"PETA is certain that Farrah, like any mother, would be horrified to learn that lion cubs used for photo ops are torn away from their mothers shortly after birth so that they can be passed from one stranger to another -- and that when they grow too big to be used as props, these animals are often abandoned at appalling roadside zoos, slaughtered for meat, or used as targets in canned hunts," a PETA representative told RadarOnline. "We hope that Farrah will stick to animal-free tourism in the future."
