After eight years together, Lil Bailey thought she’d already found ‘the one’ - that is, until he dumped her for a blonde 20-something colleague.

Well it’s pretty bad actually. First Max ghosts her and then, after weeing on a stick (but mostly her hands), a few weeks later Lil discovers she’s pregnant.

Lainey has just lost everything. Luckily one little fib (OK, quite a big fib) helps nail her dream job. Soon she's living in a stunning house by the sea, fending off obsessed fans for a retired - if far-from-retiring - actor and organising his charming but chaotic family. Yes, everyone thinks she's part of a couple, and it's tricky keeping this secret. But at least she's not looking for love: with her disastrous relationship history, men are definitely off the agenda.
