Jessica Alba takes her favourite blazer everywhere she goes.

The 'Sin City: A Dame to Kill For' actress knows she won't necessarily wear the jacket, but can't go on a trip anywhere without it because she loves it so much.

She said: ''I have this Celine double-breasted black blazer with gold buttons. Even if I don't wear it, I always bring it on a trip. I love it.''

The 34-year-old beauty - who has daughters Honor, seven, and Haven, four, with husband Cash Warren - also admitted she is ''envious'' of women with full eyebrows as she ''ruined'' hers as a teenager by over-grooming them.

She told People magazine: ''Right now I'm really into the brows. I feel like you can have nothing else on your face but a little concealer here and there and a strong brow.

''I'm always envious of girls who have [ones] that aren't overplucked because the 90s just ruined my brows. I've been on the mend ever since.

''And I for sure in the 2000s was still guilty of just making them as skinny as humanly possible.''

When she isn't working, Jessica loves relaxing in front of the TV and she's currently feeling ''really depressed'' as she's watched all the episodes of Idris Elba's crime drama 'Luther'.

She said: ''I just got done with 'Luther' and I'm really depressed about it. So I'm recovering right now.''
