The curly-haired singer is adamant the N-Dubz stars will kiss and make up despite only announcing their split last week.
Tulisa grew close to the girlband, made up of Jesy, Perrie Edwards, Leigh-Anne Pinnock and Jade Thirlwall, when she mentored them on the X Factor last year and saw them scoop victory when they were crowned winners in the show's final in December.
Putting on a brave face as she turned up to the National Television Awards on Wednesday night, Tulisa wowed on the red carpet in a strapless, hot pink, feather adorned dress.
Beaming from ear-to-ear as she posed for photographers, it appeared she was putting her heartache to one side to enjoy the night.
She got support from the girlband though as she was seen cuddling up to them inside the O2 Arena in London, where the awards were held,
after they performed You Got The Love on stage.
And it now seems Tulisa may have confided in her gal pals as Jesy told The Sun after the ceremony: 'I think they'll definitely get back together – they are meant for each other.'
Tulisa and Fazer, who were apparently dating secretly for over one year before going public towards the end of last year, were revealed to have split last week.
While Fazer has kept busy by heading on nights out with pals, Tulisa has been taking her mind off it by working on her solo album. Both have remained silent about the split on their Twitter pages.
No reasons has yet been given for the breakdown of their romance but it was rumoured earlier this week Tulisa called time on their relationship because of Fazer's 'close friendship' with Made In Chelsea star Chloe Green.
But on hearing the gossip,
Chloe took to her Twitter page and angrily insisted it wasn't true. She said: 'I just don't get why every guy who is my friend is suddenly someone I am supposedly with.. Girls can have friends that are guys! #notacrime.
'So over London maybe its time to move stateside!! #meetnewpeople #lessbulls**t #lessdrama!' she ranted.
