Gwen Stefani's commitments recording with No Doubt mean she is likely to miss her L.A.M.B. runway show at New York Fashion Week.
The No Doubt singer is expected to miss out on taking her final bow when her label L.A.M.B. shows their new collection because the group are currently based in Los Angeles working on their first album for over a decade.
A source told the New York Post newspaper: "It's really important to her."
A spokesperson for L.A.M.B. insisted Gwen hasn't yet made a decision on whether to attend her final presentation, but admitted the star is under "extraordinary demands".
They said: "Given the extraordinary demands of working on three fashion lines while also finishing a new record, it is hard to say whether she will be able to attend the actual presentation in New York next month."
Last month, it was announced that Gwen is teaming up with Target to create an affordable range of clothes for babies, children and young teenagers.
The blonde beauty will work on the collection, entitled Harajuku Mini, with the budget store, which will be a spin-off of her successful Harajuku Lovers young contemporary apparel and accessories collection and Harajuku Lovers fragrance.
She said: "Harajuku Mini is a dream come true. I've always wanted to do a cool children's fashion line inspired by the supercute and playful kid's clothing you find in Japan. The whole idea is about being creative, expressing your own individuality and having fun getting dressed. Target has given me the creative freedom to design kid's clothing that is different than most anything you usually see out there with great quality, attention to detail and most of all, available at amazing prices."
