Miles, 25, shared the same pictures around the same time and wrote on his own Instagram account, "Officially a family man!"
Krystal gave birth to a daughter weighing six pounds and 3.5 ounces on Wednesday, March 31 in La Jolla, CA, at 10:17PM PT. The baby measured 18 inches long, Peoplereported.
"She is a happy and calm baby and everything we dreamt she would be. We are still in awe of our little angel," Krystal and Miles told the magazine in a statement.
Before heading to the hospital to be induced, Krystal reportedly wrote Wednesday on her Instagram Story, "Feeling less anxious about labor and delivery than I did yesterday! If you saw my stories, you know those emotions were getting REAL!!"
Krystal also posted two nude photos of herself posing with a flower garland on Instagram ahead of going into labor.
"The final hours of this journey are coming to a close. It has been an honor to be a vessel between heaven and earth. Pregnancy is amazing," Krystal captioned the photos.
"Thank you @tiffanyallenphotography for putting together this special Glitter Baby photoshoot. Ps-On hour 18 since we got induced!! Fingers crossed @glitterbaby2021 is almost here!!"
"The best things in life happen unexpectedly," Krystal captioned a four-minute video at the time.
"The best stories began with, 'And then all of the sudden.' The best adventures are never planned. Free yourself from expectations. The best will come when you least expect it."
Krystal reportedly began dating Miles in May 2020 and the couple went Instagram official in October of last year.
Krystal said in a YouTube video that receiving a positive home-pregnancy test in early August 2020 was "f-cking bananas."
Krystal and The Bachelorette alum Chris Randone, who fell in love on Bachelor in Paradise's fifth season and got engaged during the finale, announced their mutual and amicable decision to split and separate on February 15, 2020, just eight months after the pair got married.
Krystal admitted during a December 2020 appearance on the Scheananigans with Scheana Shay podcast that "it was scary" to find out she was pregnant because she and Miles had only been dating for about four months at that point.
"Especially me still being legally tied in this marriage and having this whole public thing around it," Krystal said.
She also revealed at the time Chris had reached out to her to congratulate her on the baby once news circulated of the pregnancy.
"He texted me and said he thinks I'm going to become a wonderful mother and he's really, really happy for me and hopes that we can become friends and be there for each other," Krystal shared, according toUs Weekly.
"So we are on really good terms," she added.
Krystal and Chris released the following statement when they announced their decision to separate: "It hurts to announce that at this moment, we have mutually decided to separate."
"Never did we imagine this scenario," the couple continued, "but we've come to a point where we both need to work on ourselves... We just ask that you please respect our privacy as we navigate through this."
"The past 8 months have not been easy...I've been torn between mourning a life that could've been...and determined to fight for the future that I know I deserve," Krystal wrote on Instagram, along with a photo of herself and her two dogs.
"With respect and support for one another, Chris and I have decided to move forward with filing for divorce."
She added at the time, "We are grateful for the events that brought us to find one another, as we have been great teachers on our journey of personal discovery and growth. I believe that there can be beauty inside of pain when we have the courage to look within with compassion and a willingness to grow."
"We all deserve to live a beautiful life we love...and sometimes we realize it's time to let go and LET GOD," Krystal continued. "Thank you for the well wishes and continued support. It means the world."
Chris and Krystal reportedly exchanged vows in an intimate ceremony officiated by The Bachelor franchise host Chris Harrison at the Vidanta Hotel, and their wedding aired on Bachelor in Paradise's sixth season in Summer 2019.
A source told People last year that Krystal, a fitness coach, and Chris, a sales trainer, had been struggling for a while, even dating back to before their televised nuptials.
And Chris confirmed to Us in August that the split wasn't sudden or a surprise to him.
"There were definitely moments where there were either warning signs or there were just mixed signals," Chris noted.
Chris explained it was difficult for him to jump into another public relationship after appearing on Becca Kufrin's season of The Bachelorette without having time to process everything.
Chris also said he endured a lot of "scrutiny" while Bachelor in Paradise's fifth season was airing because he came across like a villain on Becca's season and got off to a rough start in Paradise.
"I couldn't process it or focus on that or just be able to address it because I had a relationship [and] I was engaged and then that turned into a marriage," Chris explained, adding that being in the public eye contributed to his breakup with Krystal as well.
"And the entire time I abandoned myself, which I think led to just some issues within me as well."
Chris, however, said at the time he was almost ready to begin dating again and make new connections with women.
People previously reported that Chris and Krystal's personalities didn't mesh at all and they weren't on the same page about what they want out of life.
The couple reportedly wasn't ready to get married but felt "immense pressure" to give Bachelor Nation the happy ending they had been waiting for.
Krystal and Chris' breakup came as a shock to fans because Chris had told Us in August 2019 that Krystal had decided to stop using birth control and they wanted to start trying for a family in early 2020.
