The controversial housemate, 26, sobbed as the finalists' friends and family entered the Big Brother compound on Thursday night (25 August) during a special live episode of Big Brother's Bit On The Side.
Spotting Linda, host Rylan Clark-Neal told her: "I'm gonna sit with you as you must have had the hardest month."
"It was quiet," admitted Linda, joking: "Can you have him for another two weeks?"
"He's done brilliantly," she added. "He's kept everybody entertained. He's made us laugh. I'm really proud of him."
The friends and family were all given 15 seconds to send a personal message to their loved one. Linda said: "Keep strong, Stephen. You've been really entertaining. You've made us laugh. We love you dearly and we're really, really proud of you. We can't wait to see you tomorrow and give you a big cuddle and a kiss."
Bear broke down in tears as she spoke - and tried to escape through the glass partition to see her! When Rylan went into the garden to chat to the housemates, Bear made a run towards the open door to see his mum, but Rylan restained him: "I'm telling you now, sit down or I'll chuck you out myself!"
He then tried his luck AGAIN and this time made it through the door, but the friends and family were on longer on set. Instead, he was able to approach the BOTS audience, chuck his shirt at one female audience member and then climb on Deborah the Zebra.
"Get back in here!" shouted Rylan, who seemed to be trying really hard not to laugh.
Of course, Bear was soon back in the garden!
He'd previously told housemates he was disappointed not to see his mother during the last shopping task, where housemates had to complete challenges without being distracted by loved ones. While others had messages from friends and family, Bear was confronted by ex-girlfriend Lillie Lexie Gregg.
"I'm still a f**king human mate," Bear had told James, "and what I've been through in here… I'm sitting here waiting for a message from my mum or something. I think I'm a selfish person. It's nice for everyone getting their things, it's lovely…"
Linda was joined on CBB BOTS by Marnie's mum Sharon, Frankie's mum Joan and Ricky's best friend Darren. Aubrey's boyfriend Pauly D and Renee's sister phoned in from the US.
Plenty of viewers took to Twitter during the show to share their thoughts on Bear's tears, saying it had been a very "sad" and emotional moment that made them cry. Others said it showed a different side to the divisive Bear, whose pranks and behaviour has wound up many viewers and the housemates.
