Maybe this split between co-stars Martin Freeman and Amanda Abbington -- after 15 years and two children together -- means that Sherlock (Benedict Cumberbatch) and John are finally getting together in Season 4. One of the teasers does feature Sherlock saying "I love you" to someone...

Abbington addressed the breakup on Twitter:

Freeman and Abbington have two children -- Joe, 10, and Grace, 8. They met in 2000 on the set of the U.K. TV movie "Men Only." Look at how cute they were together in 2006:

Sadly, the show must go on. Abbington recently shared that "Sherlock" Season 4 would be brutal but very funny and the whole company's favorite season to date. It begins January 1 at 9 p.m. on PBS.
