The glamour girl was pictured arriving at LAX Airport last night ahead of an expected reunion with Reid, who was already in the States to film his martial arts TV show.
Price has reportedly left her three children Harvey, 7, Junior, 4, and Princess, 2, with ex-husband Peter Andre and is said to be planning to spend ten days away from home.
A source told the Daily Star: "Kate's gone out to LA to see Alex and to pamper herself. She loves being out there and she's going to turn it into a bit of a holiday. She goes over regularly to have work done - Botox, hair extensions, the lot.
"Pete's got the kids for the next ten days while she's away, so she and Alex are going to be spending lots of time in the bedroom."
It is thought that the couple are planning to make a public appearance at the Oscars on Sunday night.
