Washington, Aug 4 (ANI): It seems Justin Timberlake is getting serious with girlfriend Jessica Biel, for the singer went 'ring' shopping for her.

According to a source, although the 26-year-old was not yet ready to propose his ladylove, he wanted to show that he was committed.

"Justin isn't ready to propose, but he wants to make a commitment to her. Justin says Jess is his dream girl. He wants to give her a symbol of his affection and love," Contactmusic quoted the source, as saying.

The couple has been dating since May, and while the R and B star is buying rings, Biel recently revealed that marriage did not interest her.

'The Illusionist' actress had insisted that spending two to three decades as a single and then devoting the rest of the life to marriage did not make a good ratio.

"What's weird is: You're single for 20 or 30 years, and you're married for like 70," Biel said.

"It doesn't seem like a good ratio, does it?" she added. (ANI)
