In a joint statement from Will and Jada, they tell Entertainment Tonight, "Although we are reluctant to respond to these types of press reports, the rumors circulating about our relationship are completely false. We are still together, and our marriage is intact."
A sentiment their son Jaden shares, as he Tweeted, "#ItsAllLies."
On Tuesday, In Touch Weekly reported that a source told the magazine that Will and Jada had decided to separate after 13 years of marriage.
A rumor surfaced that Jada was cheating with Marc, her Hawthorne co-star and character's love interest.
The couple has two children together, Karate Kid star Jaden, 13, and 10-year-old Willow, who became famous last year when her single Whip My Hair became an Internet smash. Jada is also stepmother to Will's son, Trey, from his previous marriage to Sheree Zampino.
