Speaking to the Standard about her Christmas plans, Lowe said she and Saul were going to her mother’s house in Frome, Somerset.
She said: “I will be taking my boyfriend home for Christmas which is a first, I have never taken anyone home for Christmas before.
“But no, there will be no pressure.”
Lowe – the daughter of the singer-songwriter turned designer Pearl Lowe and rock star Gavin Rossdale – has previously dated actor Matt Smith and singer Jack Penate.
Lowe also spoke about what she wanted for Christmas. She said: “I don’t want anything, I don’t need anything, I don’t want the waste – I want to think about the planet. I just want the time to spend together. I just want some old lady presents, like bath salts and scented candles. Yes I am 32, but I act like an 80 year old and I am proud of that.”
The campaigner said she was determined to get into shape in the new year following months of inactivity due to Covid-19.
“I want to get really fit again,” she said. “I feel like the pandemic has taken its toll and I am excited to get fit this year. I know that when I exercise, mentally I am happier. But any sort of going to the gym, I find it really difficult and I need some serious talking to.”
Recently, the model, who has partnered with Deliveroo and KFC, was seen enjoying a night out in London in a robe adorned with a gravy boat monogram. She said: “It is now 100 per cent acceptable to leave the house in loungewear. So I went out in some loungewear that was covered in gravy boats. We did have such a giggle.”
But Lowe said she still enjoyed the excuse to get glamorous, adding: “It is a real joy to dress up and put some good make-up on. It is all about balance.”
