The 34-year-old professional wrestler called off her engagement to John Cena earlier this year - just weeks before they were scheduled to get married - following six years together but, although it's been a tough time for her, she's hopeful that her career will accelerate in 2019.
Speaking to 'Entertainment Tonight', she said: ''I'm really enjoying being an entrepreneur [and] I'm very excited for my comeback at WWE.
''I just have this goal in my head of what I want to conquer as an independent woman and I'm going to get there. And I can't wait to be on the cover of Forbes, so look out!''
And the Nikki thinks it's important she learns how to love herself before she dates again.
She explained: ''It was quite a journey to really love myself. But I think when you go through so much, I don't want to say hate but criticism, it makes you do two things: You can even go in a way to please other people or you can take a good look at yourself and go, 'This is who I am. This is how I was made and I'm going to love it. And I'm just going to shine that confidence through.' You're better in a relationship when you fully have that self-love and love yourself and know who you are because then you're just so confident in that relationship.''
Nikki's reality TV show 'Total Bellas', which is based on her life and that of her twin sister Brie Bella - has just been renewed for another series and she has revealed the forthcoming instalment will focus on her ''new journey, just with my family'' rather than her relationship.
She said: ''It's been, as we all know, a hard few months.
''[But] the fans have been so supportive and the fact that we got picked up for a new season and people want to continue to watch Brie and I's journey, it just means so much to us.''
