"Emma" star Gwyneth Paltrow has scotched rumours that her marriage to music band Coldplay's frontman Chris Martin is on the rocks.

"Chris has been with Gwyneth this whole time in New York while mixing the Coldplay album," Paltrow's rep Stephen Huvane was quoted as saying by the New York Post.

"She's now in L.A. to be present at the Oscars and then will film two weeks on 'Running With Scissors'. Chris will join her in about a week. They are extremely happy together."

Reports had earlier stated that the couple were going through "an incredibly rough patch" as pressures of work and caring for their eight-month-old daughter Apple was getting to them.
