In a valiant effort to be supportive, Richie Sambora made it known last night that he would be there for ex-wife Heather Locklear, who entered rehab earlier this week: "Without a doubt, he's there for his daughter and her mother. They may be divorced, but they are raising a little girl they both love very much."
And despite being on the road touring with his band Bon Jovi until July, Sambora's pal insists the star will be there for Locklear if she needs him.
The source adds, "I'm sure he's available if Heather should need something and certainly for Ava."
