Aaron Carter REUNITES With Fiancé Melanie Martin Just Days After Split!

Aaron Carter and Melanie Martin are back together!

Fans of the singer, 33, are wrapping their heads around an interesting tidbit that just hit social media. Less than a week ago, Carter and his baby mama ended their engagement, and the split seemed pretty acrimonious. Now, however, the two are together again.

The "I Want Candy" hitmaker took to Instagram today to share a video of his newborn son Prince lying on the bed. The baby was wrapped snuggly in a blue blanket with white spots. His dog was also seen in the background, lounging on his bed on the floor.

"Our baby boy prince Lyric Carter Loves Christmas oldies just like his daddy," Carter wrote in the caption.

He also gave a shoutout to the 29-year-old former bartender by writing, "@missmelaniemartin I love you for giving me the greatest gift. You are an amazing woman l, my everything I am so grateful for you my darling. #fatherhood #NewParents."

He added, "thank you to everyone who has been supportive. Relationships aren’t easy but we love, cherish and adore our son. #GodBless Xo."

Martin responded in the comments, "❤️❤️❤️ Grateful for both of you forever ! Happy early birthday baby 🎂 now you deserve a little celebration. On December 7 1986 a special one of a kind was born 💕💕💕 I love you 💕😘 ! Xoxoxoo."

She got Carter's birth year wrong but corrected it by writing "1987" in another comment.

Some fans were supportive, and others were shocked.

"This is some toxic sh-t .. stay tuned for next post where he is bashing baby momma and cursing at everyone," one wrote.

"Whatttttt??? Did I miss an episode 🤷🏼‍♀️" another commented, to which a third follower answered, "you must be new here lmao. They do this once a month at least . Super healthy 😂"

"Wait so.. you went live berating her but now you are thanking her? Did you forgive her or is this just for 'the record'??" quipped a fourth commenter.

Carter announced his breakup from his fiancé on November 30, just a week after they welcomed their bundle of joy.

“Due to personal reason Melanie Martin and I have decided to go our separate ways,” Carter wrote on Twitter.

He continued, “There has been a very big lie and my sister communicating w my ex fiancé ruined everything considering she knew what angel tried to do to me in court thanks angel you ruined my family. God bless.”

Carter also blames his family, especially his twin sister Angel for causing the rift between him and Martin.

“I have the most conniving deceiving family and Melanie has been lying to me the whole time communicating with my twin sister and the family members who tried to put me in prison and who tried to get a conservatorship on me in court. I’m in shocked this is horrible,” he claimed.

On December 3, he also tweeted about their relationship being totally "over" and told his followers he was moving to Colorado.

"I cannot wait to get out of antelope valley in lancaster moving in next 20 days to Colorado I’m done with this. And it is over between Melanie and i."

Carter and Martin seemed to have patched things up quickly, as seen on his new Instagram post. Then again, only time will tell.
