Case of the Ex: Scarlett Johansson Hates Blake Lively!

Like Katy Perry sings, there will always be that “one that got away” – and for Scarlett Johansson, that one might just be ex-husband and Green Lantern star Ryan Reynolds, who is currently dating blonde beauty Blake Lively. According to reports from Us Weekly, Scarlett is fuming mad about her ex’s current love interest.

“Scarlett is pissed that he’s not under her spell anymore,” a source tells Us Weekly. “She realized what a great catch Ryan was.”

Um, DUH ScarJo! After breaking off things with Ryan, she hooked up with and dated another famous fella earlier this year: Sean Penn. Their romance was brief (a good five months) but that move apparently placed a halt on any chance for a reconciliation with Ryan.

Happy couple Blake Lively and Ryan Reynolds… Scarlett who?

“Ryan would have gotten back with her. He was so totally in love,” says the insider,” but then she flaunted Sean right after their split, and he was done.”

You snooze you lose ScarJo! Looks like things are only heating up even more between lovebirds Ryan and Blake.

“Things are great [for Blake and Ryan],” says the source. “They haven’t had a fight yet!”

Do you think Ryan Reynolds and Blake Lively’s relationship will last, or will it fizzle out soon? Would you want Scarlett Johansson and Ryan to get back together?
