Rebel Wilson dazzles as she talks Miley Cyrus' offer to become a 'trouple' on Valentine's Day with Liam Hemsworth: 'If I get desperate, great option!'

 Rebel Wilson looked worlds away from her disillusioned character as she smiled from ear to ear while promoting her upcoming film, Isn't It Romantic, in New York City on Friday. 

Even in the middle of the wintry weather, the actress, 38, was beaming with joy as she made her way out of Good Morning America. The Australian star stood out in a bold red jacket, black blouse, matching trousers, and gold flats. She looked preppy and cheerful with her hair pulled up into a stylish high pony tail, and her bangs skimming across her brows. The actress was joined for her promotional rounds with Isn't It Romantic co-star Liam Hemsworth. 

Liam cut a cool figure in a black jacket, slacks, and suede sneakers as he headed out into chilly NYC. In Isn't It Romantic, Rebel plays Natalie, a young woman disillusioned by romance, whose world turns upside down after she suffers a head injury and her life turns into a romantic comedy. 

While promoting their upcoming movie on Good Morning America, Rebel revealed working on the movie inspired her to begin looking for love, and that she had started reading dating books for advice.  

The actress also hilariously confessed to Liam that she had to have her toe nails super glued on under the sheets in between takes of their love scene. 'What was going on with me that day is that two of my two nails had fallen off,  and we were super gluing them under the bed sheets... it was from an injury from another stunt in the film, and I didn't want to tell you because it was such a sexy scene.' 

Liam, meanwhile, also opened up about his wedding to Miley Cyrus, who he called one of the sweetest people on the planet. 

'It was very intimate, pretty much just immediate family, couple other close friends, it was a really special day,' Liam said of their wedding day. 

Rebel also talked potentially going on a Valentine's Day date with Liam and his Miley. Last month, after Rebel admitted she never had a date on Valentine's Day, Miley asked her to become a 'trouple' with her and Liam on the loving holiday. 

'She said it was like a trouple date or something,' Rebel said. 

'Are you going to take them up on it?' Michael asked Rebel. 'I don't know! I think she should have asked Liam before,' Rebel said, before the actor said he wanted her to join them. 

'I'm all for it!' Liam said.

'Aww, thanks!' Rebel said.  'If I get desperate, great option!'
