Jessie Wallace - EastEnder Kat SlaterJessie WallaceKat Slater's about to make her grand comeback in EastEnders - but she hasn't quite made it as far as Albert Square yet.

In a dramatic storyline the tart with a heart, played by Jessie Wallace, is found languishing in jail by sister Little Mo.

And it's a bit of a shock to Little Mo in more ways than one - as she's been having a fling with Kat's hubby, Alfie Moon.

Meanwhile The Mirror reports that Ross Kemp IS coming back to Watford after six years away at ITV in a £1m golden handcuffs deal.

The paper says bosses are finalising his contract and will make an official announcement shortly.

If so, Grant is due to be reunited in the autumn with Phil, who made his screen comeback last night after a year on the run.

Brothers Return: Phil & Grant MitchellReunited? Phil and Grant MitchellTheir screen mum Peggy - Babs Windsor - returns in August. Letitia Dean also returns in the summer as Sharon Watts, so look out for fireworks with the Mitchells...

An insider said: "To have them back is pure TV gold." The BBC said: "Ross has been in talks but nothing has been confirmed at this stage."

Kat was last seen leaving Albert Square to take a break from Alfie after months of heartache together. But just why she's in jail remains a tightly-kept secret.

Jessie, 33, returns to 'Enders at the end of May after a seven-month break to have daughter Tallulah Lilac.

Her private life has been almost as tangled as her character's, with her marriage to fiance Dave Morgan called off earlier the year, leaving him reportedly sleeping in the car.

Jessie has apparently been looking to leave the soap when her contract expires in the summer but bosses are thought to have offered her £100K to stay until Christmas, with a huge festive plotline around Kat and Alfie.
