Corrie’s Katie McGlynn unleashes bikini cleavage as she shows off salesman boyfriend The Coronation Street cast member showed off her assets as she stripped down to her swimwear on holiday. Katie, who plays Sinead Tinker on the soap, looked stunning as she paraded her cleavage in the tiny blue two-piece. The 22-year-old blonde was posing with her boyfriend Benjamin Roberts while on a Christmas break in Thailand. The loved-up pair posed together for the camera at an elephant sanctuary. “Katie and Benji are absolutely smitten with each other” Insider Katie captioned the post: Me and my mate giving B a wash #bestday. The cute photo comes as it is claimed Katie is smitten with her 21-year-old holiday park caravan salesman boyfriend. A source said: Katie and Benji are absolutely smitten with each other. Theyve been seeing each other for a while now and their friends joke theyre inseparable.. The insider continued telling The Sun: Theyre spending Christmas together on holiday and things are going really well. Katie also posed more sunshine snaps of the couples holiday. They saw her laying on a beach as she covered up in just an orange bikini and nude shawl. She captioned it: Always deliberated with going away at Xmas but it’s not been kooky much especially with this one @benjaminrobs #merrychristmas.. Katies character Sinead has a much more complicated love situation on Corrie. The blonde knicker-stitcher is caught between two men; long-term love Chesney Brown and new flame Daniel Osbourne. Thankfully her love life away from the small screen seems much more settled.
