"And then there were 5.. The Gaines crew is now 1 stronger!" Chip announced on Twitter on Saturday morning.

Both Joanna and the baby boy are doing well, according to Chip.

"10 beautiful toes and 10 beautiful fingers all accounted for, and big momma is doing great! #blessedBeyondBelief," he tweeted.

Chip did not disclose the baby's name or other additional details.

The married Fixer Upper stars had announced they were expecting their fifth child in January. Chip and Joanna have four prior children: 13-year-old son Drake, 12-year-old daughter Ella, 12-year-old son Duke and 10-year-old daughter Emmie

Fixer Upper's series finale aired on HGTV in April. Chip and Joanna had announced in September that Fixer Upper's fifth season would be its last.

The pair had starred on the series since it debuted with a pilot in May 2013 and began airing its first full season in April 2014.

During press interviews about their shocking decision, Chip said he was missing spontaneity in his career while Joanna felt time with their growing children was slipping away too quickly.

The couple had insisted, however, their marriage was not on the rocks.

In a November interview with ABC News about why they pulled the plug on their popular HGTV reality show, Chip had said "We had four babies right before the show started and then we've had zero babies since the show started. For me, I'm really excited to go back and try to maybe make some more babies."

However Joanna didn't seem to be on the same page, blurting out a "maybe" after Chip's comments and saying they had "different answers" for why Fixer Upper was ending.

The Fixer Upper stars celebrated their 15th wedding anniversary earlier this month.

Chip, 43, had marked the occasion by penning a short poem to Joanna, 39, on Twitter.

"15 years.. where'd they go. 15 years.. I'd like to know. 15 more, to God I pray. 15 more just to make her day," he wrote.

"Happy anniversary sweet girl!"
