The fashion designer had an obvious answer when asked which TOWIE star she couldn't live without, ahead of the 17th series starting this weekend.
"My Arg," she replied, "because I love him and I hate him but I couldn't live without him. He's my best friend and when I'm not with him for a couple of days I really miss him."
Lydia also said her most defining TOWIE moment involves Arg…
"When James gave me the pair of Manolo Blahnik shoes and when the choir sung Westlife – it was me and James at our best, I was wearing a lovely vintage dress, and it was a very special moment."
TOWIE returns to ITVBe for its 17th series on Sunday at 10pm.
