Shock break-up for Big Bang Theory star!

It seems like all of Hollywood are going there separate ways this week! Following news of Sarah Hyland's split from Matt Prokop and Bella Thorne calling an end to her relationship – soon only Brangelina will be left!

Now, it has been revealed that it is all over for Big Bang Theory star, Johnny Galecki and actress, Kelli Garner. 

The couple had been dating for almost two years but ended their relationship amicably, a source told US Weekly: “Johnny and Kelli are still best friends.”

It wasn’t all that long ago that Johnny and the former Pan Am actress were seen looking very much in love in Mexico.

Johnny also attended the wedding of his co-star and former girlfriend, Kaley Cuoco, with Kelli in January.
