"I'm going to throw a bomb here... I am recording a Brazilian album and I want you to be part of it" says Grammy-award winner Ricky Martin after Emma Pask's rendition of a Brazilian Portugese anthem, Mas Que Nada.

As proof of Emma's remarkable performance, coach Joel does not stop himself from shouting "Fuego! Fuego! Fuego!" which means fire.

The said performance by Emma Pask was sizzling that Ricky Martin just had to ask her to record a song for her in his upcoming album, the Herald Sun reports.

It is to be recalled that Ricky Martin challenged Emma Pask to learn a song in a foreign language and practice a few Samba moves. The challenge came after Ricky saved her from being eliminated from the Team Joel.

The moment is such one thrilling instant for Emma Pask. Emma had been trying her luck in the music industry since Jazz artist James Morrison discovered her when she was just 16 years old.

To make Emma shriek with more excitement, Ricky told her that "you broke boundaries... I love working with you, this is a commitment."

Emma's performance for The Voice episode was part of the talent showcase of the Team Ricky.

Meanwhile, Caterina Torres, Melbourne pop singer sent Ricky Martin on the edge of his seat, literally, jumping, as she did a powerful take on Beyonce's If I was a Boy. As Herald Sun put it, "coach Martin (was) jumping on his chair like a crazed stage mother."

Caterina Torres is said to be a strong competitor for Tenor Luke Kennedy for the highest public vote. Luke had equally wowed the audience with his performance of Andrea Bocelli's Time to Say Goodbye.

Coach Delta said that Torres, "... looked like a superstar. I want you to hear that from my heart."

Coach Ricky agrees, "You are a star and (that's) why I am so proud to work with you."

Even if the majority of the contestants were able to deliver praiseworthy performances, the episode was not all in good vibes.

Coaches Seal and Delta Goodrem erupted to a tension when his team's singer Jac Stone was showered with criticism.

What particularly sent Seal to anger was when Goodrem told Stone that she "didn't feel completely engaged" in Stone's rendition of Suzanne Vega's hit Luka. She added that the performance "was too introverted".

Seal tried to motivate an audience applause in his desire for talent Stone to recover from the criticism.

Just like The Voice episode of last week, Seal and Goodrem poured out their emotions when they were already being interviewed by The Voice's digital team. Goodrem said that "Stone had pulled too many faces over-emoted during the song. Seal immediately reacts with sarcasm by saying that "you (Goodrem) do that".

The producers of the show acted quickly by stopping Goodrem from retaliating at what Seal said in order to stop any possible bickering that "was not in the positive spirit of the show."

Senior management at Nine, acknowledges Goodrem's standing her ground with grace against Seal's bruised ego.
