Is Orly ready to pop the question to KP? Looks like it!

Orlando Bloom and Katy Perry, who have been dating since January, are getting serious about their romance -- so much so that the 39-year-old is getting ready to propose, a source says.

A Bloom insider tells People that the duo are "not engaged yet, but seem to be heading that way."

Apparently the naked paddle boarder, who shares a 5-year-old with ex-wife Miranda Kerr, "always gushes about Katy and thinks she is amazing in a million ways," added the source.

The insider continued, "He would love to settle down with Katy and have more kids. He hasn't been this serious about a girl since Miranda."

But apparently the "Teenage Dream" singer's pal says the singer's in no rush to get married. "Katy's divorce from Russell [Brand] really messed her up emotionally."

We can't imagine that her on-again/off-again relationship with super lame John Mayer could have helped her much either!

Despite her baggage and past heartbreak, Katy seems to be all about her Lord of the Rings hunk.

"They've been getting along really well," adds the friend. "Katy gives him space, and they're both pretty independent. They are serious about each other and their relationship."

We're happy to see Katy happy -- especially after dating John Mayer ... he was the worst!
