Gwyneth Paltrow won't move in with Brad Falchuk until he redecorates.

The 'Iron Man 3' actress - who has children Apple, 11, and Moses, nine, with estranged husband Chris Martin - is growing increasingly serious in her relationship with the 'Glee' co-creator, but has reportedly asked the 44-year-old producer to ''neutralise'' some of the colour schemes in his Hollywood home before she will consider taking their romance to the next level.

A source told the Mail on Sunday newspaper: ''Brad's been telling friends that there need to be changes to the interiors to accommodate Gwyneth's taste.

''She seems to like more neutral colours and won't stay over too often until the place has been changed.''

While Gwyneth, 42, isn't ready to live with Brad - who she started dating last summer - yet, she recently admitted she attributes her good looks to good sex.

Asked the key to looking good, she said: ''I'm not really a 'beauty person'. I believe, as cheesy as it sounds, in exercise, laughing, having sex, being yourself. I'm not like, 'Then I use this masque that I make on my stove.' ''

And the blonde beauty admitted earlier this year she is ''feeling good'' about entering a ''new chapter'' in her life.

She said: ''I'm entering a new chapter in of my life, and I think I feel very comfortable with myself... it feels good to be more myself.''
