Aaron Carter is expecting his first child with girlfriend Melanie Martin, weeks after her arrest for felony domestic abuse.

The 32-year-old made the announcement on Instagram Live on Tuesday.

'Obviously I have a baby on the way,' he told fans after showing what appeared to be a positive pregnancy test. 'I'm going to be a busy father for sure.'

He then added: 'This is the official announcement. We're pregnant.'

He later shared a shirtless photo of his tattooed body, captioned 'dad bod'.

The news comes less than a month after Melanie was arrested for felony domestic abuse.

At the time Aaron was open about the fact Melanie had said she was pregnant, but told TMZ he thought she was 'lying'.

Talking to People magazine about the pregnancy, Carter said he was delighted.

'This is what we both want,' he said, admitting the couple had planned the pregnancy. 'We both were trying for it. I'm just focused on the future and being a dad. I want to be a good dad.

'I'm focused, my music career has been doing really well, and touring, having my clothing line out, all that stuff I have going for me that isn't necessarily just music. Family is most important to me.'

Things between Aaron and Melanie got physical on March 29 around 11pm, prompting a visit from the L.A. County Sheriff's Department.

Marks on Aaron's arms - which he also shared images of online - appeared to be from Melanie, so she was taken into custody.

Social media personality Melanie was held in custody for a number of days on a $50,000 bail, according to the site.

Shortly after the incident the pair unfollowed each other on Instagram, a move presumed by fans to imply they had split. Aaron wrote on Twitter: 'You don't have to wait for someone to treat you bad repeatedly.

'All it takes is once, and if they get away with it that once, if they know they can treat you like that, then it sets the pattern for the future.'

Aaron previously had a volatile relationship with artist Lina Valentina, who he also accused of domestic violence.

Before their blow out fight, former child star Carter and Martin seemed inseparable.

In addition to tattooing her name on his face, the That's How I Beat Shaq singer showed off a serious ring shopping session on Instagram in February, leading to speculation he was planning to propose.

Aaron's pregnancy news follows a long period of instability for the Marriage Bootcamp star, who opened up about his mental health struggles in a September episode of The Doctors.

'The official diagnosis is that I suffer from multiple personality disorder, schizophrenia, acute anxiety; I'm manic depressive,' Carter said on the show. 'I'm prescribed to Xanax, Seroquel, gabapentin, hydroxyzine, trazodone, omeprazole.'

Then, late last year two of Aaron's siblings were granted restraining orders against their brother, claiming they were afraid of him.

Carter was ordered by a judge to give up his guns after his twin sister Angel was granted a one-year domestic violence restraining order.

At the time TMZ claimed Carter began to 'scream' at the judge, threatened to leave the proceeding and declared he would just go out of state and buy more firepower.

And the following day a judge also granted his Backstreet Boys star brother Nick Carter, 39, a one year restraining order against Aaron.

Nick had claimed Aaron confessed to thoughts of killing Nick’s pregnant wife and their unborn child.
