Good lord there’s a lot of catching up to do on Ms Britney Spears this evening.

Since our last Britney post we’ve had two more snippets (‘Seal It With A Kiss’ and ‘Criminal’, both below); a glimpse at her shoot with Mario Testino for the new issue of V magazine (above); the news that her next single ‘Till The World Ends‘ is released on March 11 – artwork below – and – deep breath – MTV UK have posted an unconfirmed ‘Femme Fatale’ tracklist.

(UPDATE: Till The World Ends snippet now on Amazon.)

‘Seal It With A Kiss’ and ‘Criminal’ join the previously released snippets ‘Inside Out’, ‘I Wanna Go’, ‘How I Roll‘ and the will.I.am collaboration ‘The Big Fat Bass‘, leading us to wonder if Team Britney are going to release a teaser for every single track. You know, because the seven million video teasers weren’t quite annoying enough.

Now, let’s have a look at that unconfirmed tracklisting for the deluxe edition of Femme Fatale, shall we? Apologies in advance if this turns out to be incorrect…

1. Till The World Ends
2. Hold It Against Me
3. Inside Out
4. I Wanna Go
5. How I Roll
6. (Drop Dead) Beautiful (Feat. Sabi)
7. Seal It With A Kiss
8. Big Fat Bass (Feat. Will.I.Am)
9. Trouble For Me
10. Trip To Your Heart
11. Gasoline
12. Criminal
13. Up N’ Down
14. He About To Lose Me
15. Selfish
16. Don’t Keep Me Waiting

It’s also been announced that Blink 182 drummer Travis Barker has worked on ‘Femme Fatale’, and that Britney will launch the album with a mini-concert for Good Morning America on March 29th. Here’s her video announcement if you missed it last week:
