The couple has been married since 2008, but it was recently speculated the R&B star was ready to divorce Vince amid allegations of infidelity.

Tamar, the younger sister of Toni Braxton, let her actions do the talking when she took to Instagram on Sunday (17Jul16) and shared a video clip of herself serenading her husband with a rendition of Mariah Carey's Always Be My Baby.

However, in the caption, she quipped, "After all these years he STILL hates when I sing in his ear #Tamar&Vince".

Now Herbert has spoken out to silence the split speculation, insisting they are "totally fine".

He tells Entertainment Tonight they spent Sunday attending church services with their three-year-old son, Logan, and are now focusing on completing Tamar's next album.

"When God blesses people, there are always people who are going to try to tear them down," he says of the break-up rumours.

Meanwhile, an insider adds to ET, "(They) are doing fine and they are happier than ever."
