The pair, who wrote Niko's hit song "GOOD TIME," "have always wanted to have a family together," Niko told PEOPLE when confirming their pregnancy news in early August. The exciting news came after a difficult journey to conceive.

"From the moment I met her, I knew she would make the most amazing mother! Our path to seeing those two pink lines was one we weren't expecting, and one that led us to doing IVF [in-vitro fertilization]," Niko told PEOPLE at the time.

"After Anna's transfer, we had waited about two weeks and got the green light to try an at-home test. Before I could even lay the test on the bathroom counter for her, I saw that it was positive! After all we had been through, it was an extremely surreal and emotional moment for us both."

"Pregnancy has been such an incredible time for me," Anna said of the experience. "Because of all that it took to get here, I feel so incredibly grateful every day that I wake up and see my belly growing."

The couple even wrote a song about their then-baby on the way, "I Can't Wait to Love You."

"'I Can't Wait to Love You' is our favorite song that we have ever written together. It's about this really special time in life where you have this amazing miracle on the way and you're falling in love with someone that you haven't even met yet," said Niko.

"After finding out that Anna is pregnant, we spent hours talking about Lily and all the perfect details that will become her," he added. "Her eyes, her laugh, her smile and as songwriters, we couldn't resist the opportunity to write a song about it all."
