Fashion designer and sometime actress Frost last month (JUL05) received a $10.8 million (GBP6 million) divorce settlement from Law, with whom she has three children. She also has a child from her previous marriage to musician/actor Gary Kemp.
Frost began dating flamenco guitarist Scott in the aftermath of her separation from COLD MOUNTAIN star Law.
A spokesman says, "I can confirm that Sadie and Jackson have agreed to take some time out of their relationship.
"The split is amicable and they remain in close contact."
An insider adds, "Sadie is 40 with four children and Jackson is 24 and they are at very different stages in their lives.
"The settlement means that Sadie can start life again and unfortunately she did not want Jackson to be part of her future.
"Although she loves him very much they want different things out of life."
