Does Selena not like Ellen Degeneres?

I know this is a stupid question to ask here but I've always wondered, does Selena secretly not like Ellen Degeneres? I've noticed her show is the only talk show Selena doesn't ever seem to be having fun on. She's always so calm and non-exciting whereas on other talk shows, she always seems to be having the time of her life like when she did carpool karaoke with James Corden recently. I don't mean to be insulting cause I do love Selena. It's just that I also happen to be a huge Ellen fan as well and I just can never imagine anyone not having fun on her show.
