Justin Timberlake and Robin Thicke are preparing for a rumoured sing-off at Pharell's upcoming wedding celebrations on Saturday.
The 40-year-old music producer has reportedly enlisted the help of both musicians, whom he has produced smash hits for including Robin Thicke's Blurred Lines.
It could be a scene of musical wars at the party as Robin,36, has claimed Justin supposedly ripped of his sound with 'Suit& Tie'.
Pharrell and his wife Helen Lasichanh will be holding the party for their nuptials at The Kampong in National Tropical Botanical Garden on Coconut Grove in Miami.
The waterfront estate venue accommodates up to 130 people and costs between £3000 and £5000 to hire.
With the party taking place outside guests have reportedly been given the dress code of garden-party attire.
The happy couple got married in secret in August and have a son together named Rocket Man Williams.
Celebrity names expected for the lavish romantic affair include Jay Z , Gwen Stefani, David Guetta and Robin Thicke's wife, actress Paula Patton.
A source told Page Six some of the hottest names in music will be at the party:
'Pharrell has worked with everyone. He just produced Miley Cyrus’ album, he has worked with Beyoncé, Madonna, Shakira, Daft Punk, Kanye West and Jennifer Lopez. Half the music business will be there' they said.
If Robin Thicke does take to the stage at Pharrell's wedding celebration, hopefully the 36-year old musician won't put on a repeat of his 2013 VMA performance.
In an interview with Vanity Fair, the father-of- one revealed he knew his performance with Miley Cyrus would cause controversy, but says he was bored of 'playing it safe' with his career.
'I spent my whole career playing it safe, being a gentleman, never doing anything controversial' he said.
Robin said the raunchy duet was for entertainment purposes only and he wanted to give people something to remember.
'They told be [before] that Miley's going to take her clothes off and dance around, and she might bend over!' Robin said.
He also added: 'I just said, 'I don't care, let's entertain the people', let's give them something they're not ready for, let's make them talk.
