Doing some searching and came across this, a picture from January 2016 of Maggie with her Father (and another man in the middle).

The only text/caption I can find is in Spanish: "Las celebridades que llegan a la alfombra roja para mí Premio Verde gala en Tipi am Kanzleramt Featuring: Maggie Nixon, Bernward Geier, Robert Nixon donde"

It is meant to be on a stock photo website, however the link is broken and it goes to the stock photo site home page instead. Possibly they had the link removed?

The link should have been: https://www.alamy.es/foto-las-celebridades-que-llegan-a-la-alfombra-roja-para-mi-premio-verde-gala-en-tipi-am-kanzleramt-featuring-maggie-nixon-bernward-geier-robert-nixon-donde-berlin-alemania-cuando-31-jan-2016-97536401.html

Here is another photo of her, same dress (same event?): https://i.imgur.com/zFQBOPe.jpg

We know it's her father because he's also in an earlier pic here: https://i.imgur.com/hsLJqG3.jpg

With Bob Nixon written on his nametag? (little hard to make it out, I think that's what it says).

So anyway, I hadn't seen such a recent pic of Maggie yet, until now.

Feel free to keep digging, I found this by searching "maggie nixon" on Google images with date range ending 4th April.
