Being faced with both old footage of her and Travis Alexander in happier times and a former girlfriend who brought out her green eyed monster, Tuesday was a difficult day in court for murder defendant Jodi Arias.

The challenging 51st day of the trial  began when prosecutor Juan Martinez played a video of Jodi and Travis, shot in 2007 by friend Jacob Mefford, who told the Maricopa County Court how they were were "affectionate, like a couple."

In a still photo shown to jurors, Jodi is seen beaming with joy wearing a white hotel robe, leaning against Alexander who is kissing her on the back of the head, reported from the Arizona Republic.

The sentimental flashback was all Martinez wanted from his witness, but it was enough to get Jodi crying in court before her former Pre-Paid Legal colleague Mefford was handed over to defense attorney, Kirk Nurmi.

Another blast from the past was even harder for the femme fatale killer to face as Travis' ex-girlfriend Deanna Reid, whom he dated in 2000 before she went to Costa Rica as a Mormon missionary, took the stand.

After her 18 month stint abroad serving the church, Reid and Alexander reunited and embarked on an exclusive relationship, which was no doubt hard for Jodi to hear considering her desperation to make him her boyfriend!
