I got to compete at an intense level with one of my best friends of 11 years @natbynature in the @wwe ring, I got to compete and tag in a match with my long time partner at WrestleMania and then he proposed! (Which we all thought was NEVER going to happen lol) and then I got to compete on @dancingabc with the incredible @theartemc! And I just fell in love with dance! Then my best friend for life @thebriebella and I launched two companies @birdiebeebrand & @belleradici and they have just been a blessing and have helped give us a bigger purpose in life and that’s giving back. @totalbellas season 2 and @totaldivas season 7 premiered and looks to keep on running! So grateful for everyone I work with on this from cast to production! Then our @youtube channel hit a million subscribers! Excited to give you even more content in 2018! And just shows how the #bellaarmy continues to grow! We would be nothing without you! We love you! And then us female WWE Superstars launched a Barbie with @mattel and fulfilled all of our little girl dreams. And of course I had to save the best for last... My Birdie Joe was born and I never realized how complete she not only made my 2017 but the rest of my life. My heart would not be as warm without that little girl. So thank you 2017! Sad to see you go but excited for you 2018! I hope to inspire and empower more women through @birdiebeebrand, fulfill more wine palate’s worldwide with @belleradici, become even more intimate with my #bellaarmy on @youtube, marry the love of my life @johncena, continue to dance my heart out (with @theartemc would be great if he has time for me!
