Jennifer Lopez Does Bikinis In October [PHOTOS]

It may be getting cold outside, but the chilly weather doesn’t seem to phase Jennifer Lopez, or her bikinis.

The 45-year-old showed off her famous swimsuit figure on Instagram late Monday.

The “American Idol” judge also made a surprise appearance at Iggy Azalea’s sold-out concert in Hollywood Sunday to perform their “Booty” remix.

In August, Lopez revealed that she would team up with Azalea to make a remix for “Booty,” which seems to have been very successful and is her top song on iTunes. (RELATED: Is J. Lo Even Wearing Clothes At The VMAs?)

Lopez has been taking her “Booty” all over lately, and even closed out Vancouver’s “We Day” event last Thursday, even though she wasn’t on the roster to perform. (RELATED: Jennifer Lopez Wears All Leather To ‘We Day’)

And when she’s not surprising crowds with her performances and racy ensembles, Lopez is on the red carpet constantly. She wore this red number in early October when she was an honoree at the Variety Power Of Women event.
