The Baywatch star appeared to have split from the 31-year-old blonde after Hasselhoff's Twitter blog was updated on Wednesday (19Oct11) to read, ""So Hayley Roberts has dumped me.""
The Tweet came amid reports the model wasn't ready to commit to Hasselhoff, and it prompted the actor's followers to bombard him with messages of support.
But within hours the break-up announcement was taken down and replaced with a declaration of love for Roberts.
Hasselhoff writes, ""I love Hayley Roberts... Sorry guys not true Me and Hayley are doing Great!!""
Reports suggest the original separation Tweet was posted by a hacker.
