The Essex duo were snapped outside a pub near the ITV headquarters, where they'd just been promoting this weekend's The Only Way Is Essexmas special.
Lauren returns to TOWIE for the Christmas special on Sunday night.
"She came along to a festive meal and we had a right old-school Essex Christmas, so we were all loving life," Bobby tells us in the new issue of Reveal magazine.
Essex original Lauren made her big return to TOWIE in October, after leaving the ITVBe show in series six. She shot to fame on the series thanks to her decade-long romance with Mark Wright, who is now married to actress Michelle Keegan.
But Lauren's insisted we won't be seeing her romancing anyone on screen again.
"I won't ever have my relationship on screen again. I've learned my lesson," she told Daily Mail. "And anyone I would be with, well, it's not their style to go on a television show. It will be a more positive experience this year. No drama. I'm taking on a big sister role and giving people advice and it's all on my terms."
The Only Way Is Essexmas airs Sunday and Monday at 10pm on ITVBe.
