Mum-of-five Kailyn Lowry confirms she's expecting twin boys

Mum-of-five Kailyn Lowry has confirmed the sex of her and boyfriend Elijah Scott's twin babies.

The exciting news come less than a year after the 31-year-old Teen Mom star gave birth to her fifth child, Rio - who she shares with 25-year-old Elijah.

She also has 13-year-old son Isaac, with ex-partner Jo Rivera, nine-year-old Lincoln with ex-husband Javi Maroquin and three sons, Lux, six, and Creed, three, with ex, Chris Lopez.

Kailyn took to Instagram yesterday (6 November) to share with her 4.5 million followers the very moment she first found out she was going to have twin boys.

Reading out an email delivering the news, she excitedly said: "I don't know if I can do it! I don't know if I can do it! I don't know if I can do it!"

She then opened up the email and exclaimed: "They're boys!"

The Teen Mom alum captioned the short clip: "In typical Kail + the Chaos fashion, we have to break this into a 3-part mini-series.

"You’ll fully understand after part 3. Wish me luck."

The mum first shared the pregnancy news on her Barely Famous podcast, saying she must have got pregnant 'right before' going on holiday to Thailand, but 'had no idea'.

"So when I got there, I was eating everything," she said.

"My face was flushed, but I didn't think anything of it because I was like, there's no way. There's no way I am."

Kailyn was speaking to TikToker Allison Kuch, who is expecting her first baby with NFL star Isaac Rochell - and also happened to be in Thailand around the same time.

"We were not even near each other, but what are the odds?" Kailyn said.

"And then I guess we both came home with permanent souvenirs."

Allison then said: "Wait, you came home with a permanent souvenir? Oh my God, why did I not know this? We both got pregnant in Thailand."

After quietly welcoming her youngest, Rio, Kailyn told People: "I wanted to be able to tell my own story on my own terms and kind of share what information I wanted to share instead of being within a contractual obligation or storyline."

She admitted that she wasn't necessarily trying for a child with Elijah, but said the news came as a 'pleasant surprise'.

"As chaotic as it was finding out about being pregnant again, he's been such an incredible baby that it really was a true light at the end of a really dark year for me," she said.

"He has been really a joy for all of us."
