Sorry, ladies -- one of R&B's most eligible bachelors has officially been taken.
Ne-Yo caught everyone by surprise when he announced that he and his fiancée, Crystal Renay, are expecting a baby.
The image Renay is holding in Ne-Yo's Instagram post is subtle, but a source confirms to ET that the model is pregnant.
Renay also posted a photo with the caption: "Rest your soul chocolate, I'm watching over your heart now," that hints at their new marriage.
The 35-year-old singer has two children -- 4-year-old daughter Madilyn Grace Smith and 3-year-old son Mason Evan Smith -- with his ex-fiancée, actress Monyetta Shaw, who currently stars on VH1's Atlanta Exes.
Shaw has been very open about her relationship with Ne-Yo, who she started dating in 2009 and broke up with in 2013, two years after their initial engagement. She said that she got her tubes burned because they didn't want any more children, but they are no longer together, meaning she can't start a family with someone new if she chooses.
Ne-Yo has defended himself on Instagram, saying: "I've made my apologies to the people I feel I wronged. I was forgiven by those people. Anybody else passing judgment on me for my past mistakes and immaturities is more than welcome to it."
Ne-yo and Renay began dating in early 2014. This will be the couple's first child.
There have been a slew of secret celebrity weddings this year, including Jennifer Aniston and Justin Theorux. Relive the Friends' star's nuptials in the video below:
