In surprising news Monday afternoon, Robin Thicke and Paula Patton have announced they are ending their marriage, which has spanned almost a decade.
"We will always love each other and be best friends, however, we have mutually decided to separate at this time," the singer and the actress told People.
The pair, who first met when Paula Patton was 16 and Thicke was 14, have been married since 2005 and welcomed son Julian Fuego in April 2010.
Thicke, 36, long had been very expressive about his marriage to Patton, 38, saying last fall, "We're pretty sure we've loved each other for a few lives."
Last year, both rose to new levels of fame, thanks to several big movie roles for Paula and Robin's hit song "Blurred Lines" and Miley Cyrus Twerking.
The duo's split either comes as a huge surprise or not at all, depending on whether you believe Thicke's sleazy schtick is just a schtick ... or actually real.
In that respect, there's little doubt the lines remain very much blurred.

Publicly, Paula Patton not only stood by Robin Thicke, she doubled down on the strength of their union, supporting him vocally at nearly every opportunity.
She dismissed cheating rumors, was cool with him Twerking, and even said the "Blurred Lines" video with nude Emily Ratajkowski was a huge turn on.
Clearly there was some legitimate trouble in paradise, however.
Perhaps the crooner really did mess around with Lana Scolaro or someone else? Or they just want to go different ways after half a lifetime together?
