Trivia

Her grandmother named her after the character Jenna Wade played by Priscilla Presley on the 1980s TV drama 'Dallas'.

In an interview with Gerard Gilbert of The Independent (UK newspaper), she said of the name change from Jenna-Louise to Jenna, "The boring truth is that people have never really called me Jenna-Louise and I just found it very strange because I started to do more interviews and go places where people I didn't know kept calling me Jenna-Louise. It sounded odd to me.".
