Ariana Grande fans called out a major blunder in the newly-released first full trailer of the Meet The Parents sequel, titled Focker In-Law.

The singer, 32, plays Olivia Jones in the upcoming movie, which sees Robert De Niro, Ben Stiller, Owen Wilson, Blythe Danner and Teri Polo reprising their roles from the previous three films in the beloved franchise.

Jones is a former FBI negotiator who's meeting her boyfriend Henry Focker's (Skylar Gisondo) family for the first time.

While tough-to-impress patriarch Jack Byrnes (De Niro) warms up to her surprisingly quickly, her potential future father-in-law, Greg Focker (Stiller), is suspicious. 

At one point in the trailer the two decide to race on bikes, with Greg causing her to fall off after hitting her bike on purpose. 

However, upon closer inspection, fans joked about a big oversight, as the person falling off the bike appears to be a stunt double and not Grande. 

'Not a good look when you can see the stunt double in a trailer for a comedy movie,' one wrote.

Other fans complained about some scenes looking like they were shot in front of a green screen.

'Was it really that hard to put then in a real room? Why are they clearly just sat in front of a green screen?'

'Why does everything look so cheap and fake now? Cinematography standards have nosedived,' another added.

'Yikes,' someone else wrote in response to the trailer. 

'Nah man, leave this series alone now. cant beat meet the parents and meet the fockers. should’ve stopped there!'

The trailer - which also saw Grande passionately kissing her onscreen partner - starts out with her character taking Jack's famous lie detector test, suggesting she will be joining the family.

'I test all the potential family members with this machine,' he tells her.

The session is interrupted by Greg, who also once was subjected to the same lie detector by Jack.

'Funny to be on the outside. Used to be in the hot seat,' he joked.

Olivia then asks if he wants to throw any questions at her. While Jack shakes his head no, Greg takes the opportunity to ask her if she thinks he holds his son 'emotionally hostage.'

She answers with surprise honesty, saying, 'I mean, yeah. You call him Wee-Wee.'

The trailer then cuts to Greg picking Henry up from the airport and yelling Wee-Wee. Another scene shows Olivia asking Greg if the nickname is 'like a joke about his wee-wee.'

'No, no jokes about Henry's little penis,' he quips, before adding, 'I mean, not little. You probably have more up-to-date info on it. I haven't seen it for a while, so.'

Henry then cuts him off, begging, 'Dad, please stop talking.'

While everyone appears to warm to Olivia, including Jack's dog, who at one point licks her face, Greg continues to have reservations.

After Jack tells the family that dogs can 'tell more about a person's character than a human could', his dog goes after Greg.

Jack then tells Greg that he previously questioned whether he was good enough to marry his daughter, but in comparison, he calls Olivia a 'powerhouse.'

While taking an ice bath with Jack, he expresses his worries about Henry saying that he's 'so innocent' while Olivia is 'trained to manipulate people'

Things boil over during the bike race, with Greg knocking Olivia off her bike.

'How do you bond with an emotional puppeteer?' Greg questions her.

He further rants, 'I won't be your little Pinocchio, Geppetto. Evil Geppetto. I'm a real boy.' Then, while trying to exit the room, Jack's dog attacks him, jumping right on his face, as Jack complains, 'What the hell is the matter with you Focker?'
