To play devils advocate I have the opposite opinion.I think Celine married young and the whole Insta thing wasn't in existence.With the past few years she has gotten popular and has so many opportunities for travel,nights out,free clothes,partnering with brands etc She has gotten a taste for it.She is torn between her success/single girl life and motherhood.
That marathon training alone took up a massive chunk of family life.I felt really sorry for her though out with that dose Anna O' Connor the week before Christmas.Relationships or fling wise I don't see her having any interest.
