Seems so, by all accounts it was around 2015/2016. 2016 is when she dropped out of her acting school, possibly went dark on Facebook and stopped answering friends if you read through the above stories. They were aware she met a guy around that time and papers say she moved in with Gordon that year as well.
Might be his doing, though from the way she abruptly quit acting school after a row with a teacher, it might also have been a unstable period of her life in any case.
If we can guess from the Facebook photos in 2020, assuming they were recent I'd guess she started to have kids with him around maybe 2018? Now he is a registered SO, and so will be managed via MAPPA, I would say without other offending at level 1, but let's say he's level 2 but has no offences against kids. Doesn't mean an automatic protection order, however say SS did decide he couldn't be around a baby of theirs (or not unsupervised etc) due history/ more present concerns.
However, unless she has significant issues of her own, usually she would be allowed to keep them, living apart (which she has plenty of money/support to do comfortably) AND if SS is convinced she would actually safeguard her kids effectively. She has the resources to fight SS, far beyond most mothers in her position. The fact she can afford the best lawyers and make any accomodation SS could ask for - yet still (it appears) doesn't have her other kids and is running with this one... Well it's concerning to say the least.
