She's rumoured to have been embroiled in a feud with Countdown host Anne Robinson. 

Yet Rachel Riley looked in high spirits as she left the show's studios in Salford's Media City on Monday after filming the show - albeit separately from her co-star.  

The mathematician, 36, was seen beaming broadly as she headed home after another action-packed day of filming. 

Rachel turned heads on her exit as she donned a fluorescent pink padded jacket that she paired with a matching beanie hat. 

The mother-of-two donned black leggings and white trainers, but added another pop of colour with a printed tote bag.  

Rachel recently returned to Countdown from maternity leave after welcoming daughter Noa into the world with husband Pasha Kovalev, 42, in November. The couple are also parents to daughter Maven, two.

Stepping out later in the evening was Anne, 77, who appeared to be feeling the cold as she wrapped up in an oversized dogtooth scarf.  

Last year it was reported that Countdown host Anne was at loggerheads with Rachel and the show's lexicographer Susie Dent, 56, with an 'uncomfortable atmosphere' erupting since Anne took on the role of fronting the show.  

Staff at Media City claimed that off-camera, there was tension over Anne's 'rather grand ways', which earned her the nickname 'Queen Anne'.

In October Anne reportedly turned off Rachel's microphone on set after becoming irritated by the her small talk.  

According to The Sun, Anne became fed up of listening to Rachel chatting to contestants ahead of going on air, turning up at the last minute and being on her phone too much.  

Rachel then reportedly told crew that she 'completely disagreed' with being silenced after the incident.

A source told the publication: 'It's safe to say there's no love lost. Anne is famously known for two things: her dislike of noise and time-keeping. She'll tolerate neither.  

'Anne also has tinnitus and cannot bear excess sound. Rachel, with her big heels and even bigger personality, can be quite loud on set. Rachel used to chat to contestants before every show, and Anne found it hugely distracting.  

'She felt she couldn't do her job properly, or bond with the contestants to help them to relax, before the cameras started rolling.

'The tension was palpable. Anne finds the whole thing hilarious.'

Representatives for Anne, Rachel and Channel 4 were contacted for a comment at the time.  

Asked directly about the feud, Anne, who took over from Nick Hewer on the Channel 4 game show in June, said: 'They're brilliant - both of them actually. Every time I'm astonished how she [Rachel] does that adding up and subtracting - just seconds, absolutely seconds, amazing.'

Anne added: 'I hope I'm always described as difficult, awkward, tricky, impatient, menopausal, any sort of pejorative, grumpy.'
