Kim Kardashian has let a lot of photos speak for her in recent weeks, but now the reality starlet is back to doing interviews, opening up about her life now that she's become a mother to 4-month-old North West.

Ahead of her birthday on Monday, Kardashian, 33, gave her first interview to London's Sunday Times Style supplement.

The 'Keeping Up With the Kardashians' star chatted about the importance of looking good, saying she gets dressed with a little help from her man, rapper Kanye West.

'You want your guy to think you're really hot,' Kardashian told the paper, according to Us Weekly. 'I'll put something on, and he'll say, 'No, that doesn't look good', and I'll trust him.'

One thing West, 36, is pretty happy with is his girlfriend's bikini body. The rapper proudly tweeted 'heading home now' after Kardashian posted a racy photo of herself in a high-cut white swimsuit.

'I haven't exercised a whole lot so far, just because I've been busy with the baby and I don't want to leave her,' she said, crediting the Atkins diet with her weight loss.

'I still have some (baby weight) to go. ... It's just about staying healthy - it will come off.'

In the meantime, Kardashian is showing off her new motherly style. She and West have been staples at fashion week events, flanking designers and getting gifts from the biggest names to clothe their baby girl.

In fact, North has already a cultivated sense of style.

'I want to dress a little lighter colorwise,' Kardashian told the mag. 'I think North looks cute in light colors, and then I want to wear light colors. ... North doesn't typically wear pink, though. She wears mauve or blush, not, like, typical baby pink.'
