This is so adorable! To celebrate Valentine’s Day on Wednesday, Feb. 14, Chip Gaines took to Twitter to post a sweet message about his marriage to wife Joanna Gaines. “No such thing as a ‘perfect marriage.’ For me, it’s always been simple: commitment. Every morning I wake up committed and pray that she chooses the same. And so today, again, I choose my beautiful bride. To have and to hold… till death do us part. #HappyValentinesDay sweet girl!” the 43-year-old star wrote.

Though Joanna, 39, has yet to gush about her hubby of 15 years on social media for V-Day, we definitely know the two are so in love. During an exclusive interview with Closer Weekly, a source revealed that Chip and Jo’s marriage is more blissful today than ever before after they recently announced their fifth pregnancy. “Chip and Joanna are happier than ever,” the insider said.

“Chip is so crazy in love with [Joanna] even after all these years,” the source said, adding that the HGTV star will “spoil her rotten” while she’s expecting. “He’ll be front and center during her pregnancy, waiting on her hand and foot,” the insider shared. Jo is thrilled to be pregnant again, but now that their lives are busier than ever, the mom-of-four can’t slow down while she’s expecting. “After four kids, she pretty much has this pregnancy thing down pat. Plus, she’s a very organized woman with tons of energy so she’s up at 5:30 a.m. hitting the ground running every morning, even while pregnant,” the source told Closer.

“Joanna always has the attitude that God will take care of things if you do your part, and having another baby has always been part of Chip and Joanna’s plan. Up until now, she wanted to concentrate on launching their various businesses so when the time was right she could step away knowing the groundwork was laid for their ventures to run without her constantly overseeing them,” the insider said. Happy Valentine’s Day, Chip and Jo!
