Say it ain't so!

Michelle Williams and Jason Segel, who were one of Hollywood's most adorable couples, have broken up, according to Us Weekly.

The pair apparently split up earlier this month, as the distance between them was getting to be too tough. 

Michelle lives in Brooklyn with her seven-year-old daughter Matilda, and Jason is based out of L.A. to film How I Met Your Mother.

Michelle  who was nominated for an Oscar last year for My Week with Marilyn  and The Five-Year Engagment's Jason Segel had been dating since early last year, with the public learning of their romance in March 2012.

This split is fairly shocking, as they had seemed to be doing well recently. The couple had been spotted on vacation in Cancun with Michelle's pal Busy Philipps in January. 

In October, the two reportedly bought a Brooklyn loft together, and Matilda  Michelle's daughter with the late Heath Ledger  was said to be very close with Jason.

Sources had revealed as early as June 2012 that the couple was "totally in love."

Needless to say, we're pretty shaken up by this news. If anybody needs us, we'll be in the fetal position, trying to understand why life just doesn't seem fair sometimes.
