The R&B star and her manager husband, Vincent Herbert, reportedly became embroiled in a heated domestic dispute at The Ritz-Carlton on Sunday (21Aug16), prompting a friend to report the alleged attack to emergency services.

According to, Herbert had left the scene by the time the call was made, and it's not clear if cops were able to speak to the pair to clear up the incident.

However, the couple, which has been married since 2008, seemed to be back on good terms on Monday (22Aug16), when Tamar and Vincent were spotted arriving hand in hand at Los Angeles International Airport.

They refused to comment on rumours of a "ruckus" between the pair when questioned by a TMZ cameraman, and instead just smiled and offered a thumbs up, suggesting all was well.

Tamar, the younger sister of Toni Braxton, and her husband have been dogged by speculation of marriage trouble for weeks, after rumours surfaced of Vincent's alleged infidelity.

He previously spoke out to silence the split claims, insisting they are "totally fine".

He told news show Entertainment Tonight, "When God blesses people, there are always people who are going to try to tear them down."
