The Mentalist Season 7 is yet to premiere its final season while fans can't wait for more of Patrick Jane and Teresa Lisbon romance.

However, there is a bad spoiler for 'Jisbon' fans as rumours of a love triangle is abuzz on the internet.

The latest news is, the love paradise of Patrick Jane and Teresa Lisbon may face an uninvited guest as the fan favourite show will add a new female character named Michelle Vega, TV Line reported.

The website report reads:

"A new woman is about to enter Patrick Jane's (professional) life. The CBS drama is casting the series regular role of Michelle Vega, a rookie FBI agent who is a student of combat and weaponry and is unfazed by high-pressure situations."

The latest character will reportedly enter the show as a rookie FBI agent, who would do anything to impress her bosses.

According to Christian Today, Vega's modern way of solving crime will create a difference between her and Jane, who uses unorthodox methods.

Fans are well aware that Jane's ability in solving crime is beyond doubt but will the clash of ego turn into something else in the future episodes of CBS's popular drama?

Breathcast suspects that, there is a possibility that this hate chemistry between Jane and Wega may trigger into a love triangle, which will create tension between Jane and Lisbon.

The Season 6 finale brought smile on fans face when Jane broke the airline security to stop Teresa from flying away to Washington D.C. with agent Pike.

The finale ended with a romantic kiss between Jane and Lisbon.

The Mentalist Season 7 will be back during fall this year.
