Rebecca Adlington and Mark Foster have been getting on swimmingly during their time in Rio, and it hasn't gone unnoticed by Helen Skelton. The trio are presenting the BBC coverage of the swimming events throughout the Olympics, but the rapport between the former Olympians has been diverting the attention of many viewers away from the pool.
Many fans have taken to Twitter to comment on the "flirty" relationship between Mark and Rebecca, while some noticed that the 27-year-old appeared to touch her co-host's leg under the table while they were live on air over the weekend.
